At first it made me think of a Tesuri with the colors, but then the head pushed me over to thinking Meiko. xD
Looks like its right front leg is too short - shorter than its left. I know the left one's stretching out more, but there's still too much difference between the lengths from elbows to paws. Its hind right foot looks funny too, like it's tucked in too much or something and its heel doesn't protrude enough.
I'd say pushing the shadows mostly to the right and having a few lighter ones on the left may help with the mane. At the moment its shading seems pretty random, which confused me about where the light source was at first.
It also seems a bit weirdy that we can see the pokey thing on the left ear from this angle. It's like the right one's below the ear but the left is sticking out and up.
Quite a lovely creature though, and awesome pose. I just wanna liek, ruffle up its fur or something. With my weirdy ways of showing love. 8D
... I've no idea if this counts as nitpicky. x3 With crits I'm always like. 'La-dee-daaa. Oh, I'm sorry - I rambled. O:'
