Here we got nearly simplest part of the face(this will change later). The nose is usualy represented by a single line. From the front view you see only it's shadow(doesn't matter on wigh side of the nose).When drawing the nose from 3/4 view it looks like line that only matches the highlight of the nose(sometimes here the shadow is too). The form of the nose often defines the personality of a character. A strong nose means it'll be a man(often a fighter), a large nose means it'll be a liar(like Woodchuck form Loddos War).
When making the nose small and soft it'll most of all be a woman.
