G4 MLP Anatomy Notes - Nose

Update: Jan 2, 2013: Changed name of series for 'marketability' reasons and added a few more tidbits.
Dec 2 2012: Expanded on ponies resembling wolves, and went deeper into explaining the slant-face problem with FiM-style.
Nov 17 2012: clarified some points.

Was originally gonna write what I know so far about the entire head which includes the eyes, but it seems that would make this tutorial HUGE. I thought I would just cut this down to just talk about the nose which seems to me as one of the more defining characteristics to somebody's pony style.

If there are stupid errors, bad phrasing, or anything else which makes these notes less awesome, don't be afraid to point it out.
