This is a beautiful character! I like the design and features a lot
It looks as if this character is really tense though, if that's what was intended then I'm sorry lol. The left front leg could be a bit set back and not so stressed near the top. The right front leg as a sort of unusual shape, the shoulder part doesn't show like it should. The hind legs look gorgeous.The neck looks a little strange to me- it seemed as if it's small at the bottom and bigger at the top.
Overall this is a very nice piece! I honestly couldn't see anything to critique until I looked really really hard at the picture X'D I love the shading.
