was curious how I went about human faces, profiles specifically. To understand the profile you gotta understand the front. Anyways, I hope this is legible and understandable... I'll go over the main points again just in case:

1) The face is separated into three sections,
a) Forehead - hairline, eyebrows
b) Eyes, nose, ears
c) Mouth, jaw, chin
2) The ear orients itself on the same line as your nose (generally).
3) The corner of the mouth lines up with the pupil.
4) Generally there is an eye width between the eyes.

It really does help to look at people and see how their faces meshes together. If I am unclear feel free to ask me questions, I will do my best to answer :P
