Man, this looked like a -photo- from thumbnail! You laid the lighting down well. Especially the highlights on the hair. My only qualm about the light is that it seems greenish, but it looks like it wanted to be yellow. Maybe it just needed a slightly more orange shade? Maybe it's supposed to be greenish? I don't know. So I'll shut up about that. :)

Nice motion in the dress, too. It falls over the body in an appealing way, I think. Last but not least, I like the perspective on the raised arm there.

I liked the sketch of this when I first saw it (that foreshortened hand IS nice!)

I'm a little mixed on the colored version... I think pushing your darks (under the skirt, for instance, and on the socks) might give it added drama. I'm also not sure about hwo I feel about the sketch lines still being in there; they don't look as well-cleaned up as they could be. Even colorizing those lines might make it less "I didn't clean it up" to "this is stylized motion, folks!"

It'd definitely a well-executed drawing, though. Melikes.
