Pretty good, nice detail, smoothly animated, the only things I don't particularly like about it are that the colors are kinda bright and perhaps just a little too desaturated, and the face. The face is the most important part of a person, it's the main thing people will normally focus on when looking at someone else. By making it disproportionately smaller than the body you're giving it less emphasis than it deserves, and it's harder for the player/viewer to identify with the character. You may have known that when making it, and intended for it to be that way, but I just don't like it.
Actually the colors are probably fine, I just have a preference for darker colors. It is way better than anything I could do, I would say it's a great sprite if it weren't for the face.
