A tiny nitpick: the left arm looks like it's a little bit too long.
But other than that, judging by this artwork, it looks like you know how to draw anatomy well, no weird-looking hands or legs, so it might just be an oversight.
Btw, I like the way you colour, how did you do it? It looks like it's been drawn and painted. Which makes me wonder.. did you draw this on paper or is it digitally drawn and simulating paper texture?
