Anatomy

You can change the skull however you want, it depends on your style :3 

I told you I was gonna do more with that style :3
so... this is sortof my anatomy study
I mixed up our cute little fandom pony with normal horse
also wanted to show y'all that ponies don't consist... (right word?) of circles :3
should make sense :3
hope I thought you guys something!

This may not be 100% accurate, but it's as close as I could get. search "horse skeleton anatomy" or something like that and you'll get plenty of better real horse references

i don't always use the horse anatomy either, and I have respect to all people who don't wanna cross mlp ponies with horses/wanna have a (close to) realistic style :3
just thought this might be useful to people who are interested in it :3
