Many times when we start drawing faces we think a lot about the question of perfect proportions, for example, that the lips go from the middle of the iris to the middle of the iris of the other eye. That the ears reach where the nose begins, etc. These facts can be useful, but in my opinion also boring.
I think art is about showing our interpretation of things and making them how we perceive them. Our face is asymmetrical and we all have peculiarities that make us special and interesting, those peculiarities can get lost when trying to make them fit the “rules” of proportion of the human body and instead of our illustration looking realistic, it can end up looking soulless.
To have good proportions when making something using a reference, it is best to use techniques such as putting your arm straight in front of you while holding a pencil or something that can serve as a reference.
I had a teacher who always said that we see human bodies and faces every day, we carry the proportions engraved inside us, we better concentrate on capturing gestures and emotion, I liked this perspective, but in the end everyone has their own criteria and is free to follow the parameters that best suit them.
