The distance between parts of the face. This is the raw data and indicate the average of everything. There is universal metrics for attractiveness and non attractiveness in term of organisation even though there is not only that for sure. Some ratio can indicate certain mechanics, that will be form fast holistically. The ratio will give a lot of insight about the type structure.

Certain emotions can cloud the face reading and put it toward more positive or negative readings. This can give you clues on some parts of their personalities because of the way they express emotions. If the person expresses themselves, why they might hide a specific emotion, are they comfortable sharing emotions, etc. Variations of feeling and extroversion are to watch there.

This is how you interpret the data holistically. It will be bias, based on limited experience, implicit and you will judge it. You will associate traits, and positive negative associations. Better be conscious of them if you want to be a good visual typist. 

In your environment you will spot inconsistencies. The same thing applies to face reading. You will see ornaments, meaning ways to hide the face or diminishing it or accentuating it. Be aware that you might be trick by that. 

We can see when people don't feel well and when they are angry. There are some clues and some people can be better at spotting them. We scan that in our environment to see if we can trust someone and how to act depending on the context at hand. 

We know animalistically when someone is more introvert. Often time the person gives less energy outward and we see that the face and gestures are more concentrated inward and want to hide. Often time introversion and feminine might be interlink because we associate them both together. Delicate and escapist traits are more feminine and also more introvert.

Average of the people you live close to. Even if there is a universal genetic coding of what is normal or a threat. We can summarize that normal aspect by the average of people, the average ratio and the average vibe of your experience base to some degree (hard to tell) on universal/genetic underpinning. Also if the person is wearing particular clothes or something. The most normal person would actually be consider attractive. Here I am pointing towards features that are consider in the norm within your internal compass. But hard to say what is actually normal. 

We are drawn and are more able to trust people that seems to be in a good state. It can be laughing, smiling, expressing emotions. Extrovert and people who are more able to express themselves are more easily spot when they are in a good state. 

Extrovert people have more large and masculine traits often time. We see that the metabolism is built to engage with the world and to express oneself to it. It's more huge frames and more exposition to the outside. 

We compare people we see everyday and we can spot when someone looks more different than people we are used to see. We often time, trust less the people who are more different. 

The neutral state depends a lot on the context. It may be positive for some and other not. When you should express feelings, people will trust you less, but when it's for better decisions people will trust you more (depending on the circumstances). Being neutral is associated with introversion and more thinker traits. 

It's a more rough and combative frame. Often time quite stoic and somewhat serious that command respect and some sort of authority. The masculine frame is large and strong. It is associate with extroversion and being capable externally which is associate with sensory and thinking often time. 

We tend to evaluate and give more positive traits to people that we find attractive. Often time we prefer people that are similar to what we are use to, but at the same time have more beautiful traits of the one valued. It depends on the different sexes, the culture and the person's taste, but there is still a universal and biological ratio of attractiveness.  

Often time serious demeanor and face are access as a more capable person but also less emotional. We don't know where they stand so that can be distrusting and intimidating. It's a little bit like the neutral state. 

More delicate, nurturing and beautiful traits are associate with the feminine. It's more little and elegant frame with the demeanor and gestures that are delicate. We associate mystery, rarity, nurturing and sensuality with feminine traits. More introvert and feelings traits. 

We get repulsed by people who seem dangerous, out of the norm or express states that can't be trusted. Exaggerate or underdeveloped facial features and a vibe that is unattractive. Maybe it's the people that are opposite of you or are too similar which make you repulse by them. 

People that have more gentle traits with some abnormal facial features can be considered naturally funny. Often time people like that in a good state can seem like a clown. People who look like the average but with a few funny features (exaggerate eyes, nose) without being so much abnormal or hideous will be considered funny universally. 

We associate older people with more health problems and we tend to see them as less beautiful. They are the reflection of the degenerate body we will have in the future. But having older features have impressions of wisdom and experience. Age is a pretty straightforward association. 

The eyes are the gateway to the soul. It often symbolize good and evil. This also means intelligence, light, vigilance, moral conscience, and truth. It is how people focus and give their attention. The way the eyes are made often time give letters indication (N, S, T, F) and if the person is an observer or a decider. Decider have eyes that are more zooming in and out like camera lens while observer have conspiracy lunatic eyes. It also give major clues if the person is Oe or Oi and if the person is on the Ni Se axis or Ne Si axis. This is actually probably the most important part of visual typing outside of animatronics and face structure. The color of the eyes can be illusive. 

Ne Si axis have a bubbly deer eyes aspect. While Ni Se axis a more hunter/syren aspect. This can be illusive because of eye colors, introvertness and masculiness. Introvert and masculine types often have more intense eyes. Oe eyes scan the environment and are more round. Oi eyes are more rigid. Sleep eyes often have more water in the eyes or around the eyes. Play eyes can have a pseudo Oe quality. Fi Te axis people often time have more emotional eyes. Even if the Te dom or savior can have very hard eyes that seems to suppress emotions in some case (double activation or M Te). Fe Ti axis people can have emotional eyes but it seems more distant in the fog. Often time NF eyes are more emotional, soft and fairy like while ST eyes cold, rigid and realistic like. Most people have shades of both.  

Eyebrows reflect our heart, our sexual energy, our relationship with our partner, our relationship with our siblings and our power, career and work style. I often time see the Te Fi axis having more accent on their eyebrows. It is also connect to emotions since we often time express with our eyebrows. The predator and prey is often time associate with eyebrows. Also focus and anger. Its seems to be an extension of the eyes in how the upper face is express. 

Long or big eyebrows correlate with emotional people. Often time strong willed in some fashion. Double activate Fi (strong willed in the Fi sense ?), mopey observer double activate Fi more particularly the CS EXFP (more MM sleep side) often time have long and dark eyebrows. Te dom or savior (mostly visual and entj) have eyebrows that go up. My theory is that Te Fi axis express more with eyebrows. Te velocity of thinking and Fi personal feeling and drive express themselves in that way. The only Ti Fe axis that have some clustering of big eyebrows are the Istp Ti Ni and the Enfj. They are rarely long though, mostly big. Males also have bigger eyebrows on average because of higher pilosity.

*Bonus, Eyelashes: often time more feminine (FF, FM), feeling type will have longer eyelashes.  

The metaphysical meaning of the forehead is illustrate as the seat of perception. The forehead is the center of conscious awareness, which is where the understanding of truth seals. The frontal cortex is associate with thinking abilities and perceptual organisation. It includes more evolve cognitive abilities. 

I personally see ExxP and thinker (particularly Ti) have big forehead. I see that Ne dom have pretty big foreheads. Also males, and more masculine  types tend to have bigger ones. It's seems that Oe with the accumulation of info have more dopamine (inherently a frontal cortex hormone) going in the frontal cortex which develop more programs. Often time IxxJ and intuitives forehead are long particularly when they are double activate on Oi and are Ni. IxxP have little foreheads and ExxJ have lion head. Ti can have significantly big forehead particularly if they have lots of Oe and if it's Ne. ST often have a head that is characteristic of blockheads, a soldier/worker like quality. While NF or NT seems to have a fantasy head that seems alien like and not clean at all especially Ne. Play saviors or extrovert have more rounded heads. People who seems to have a develop forehead with veins are NT. We can see this in Ne dom or Ti dom or Ni dom mostly.
