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.

This is where simpler, more abstracted art styles come in. Show-style gets away with it because it's a style which people normally don't look closer and realize how silly it is. Instead, I realize they probably made the nose like that to get away with smaller mouth and nose, much like actual cartoonists have great freedoms with regular anatomy to create more interesting characters. More realistic styles depend on better understanding of actual anatomy since people are gonna look at those more literally.
I think my avatar (at the time of writing for anyone who reads this comment in the future) shows where I am at with coping with non-sensical form with 3/4 noses. I find that it's largely trial-and-error but with the understanding that noses should be kept small and the shape should probably should not try to stray too far away from show-style at the same time.
For the most part, the best approach to figuring out this problem is just... do your anatomy homework. Learn from anatomy of both horses and humans.
Just one thing, though; You spelt 'interesting' incorrectly where you said 'I've revealed an interesting mistake'
Also, Mr. Scribbles is best pony
i cant wait untill the next one.
Although I must say, drawing these noses are remarkably challenging... aren't they?
Mr. Scribbles ftw.
