Thank you for the comment an the edit.
I dont how I shoud apply aa on that small forehead area where there are solely broken lines.
Regarding the edit I studied it and stumbled upon some changes I agree with some I disagree with and some that I dont understand.
About the foot, yes it is supposed to "hop" forward, this is due to the sprites not being animated in the game, so I tried to make the poses "dynamic".
Considering the teeth I reworked them once more so the cartoony look(mainly the scharp zig-zag line) is completely gone now, and that made the eyes the only cartoony element so I gave them volume to prevent the styles from clashing, so the sprite is now completely realsticly I guess.
What I also changed are the whiskers I redrew th left ones and changed the hue to a blue one, furthermore I reshaded the backside of the mane to make it clearer that they're being inderectly lit and I slightly adjusted the nose.
I dont get what you did with the ear and what you with the outer lines of the mane though.
Anyway here is the updated version.

EDIT:
I'm gonna go ahead and call this one finished.
I've updated the first post, I guess it s time for the next sprite, right now its a rough sketch, critisicsm especially on anatomy/perspective is most welcome.
