love her hair! pretty girl.
think it would be better with a lighter background, since her clothes and hair are dark. her shape is getting lost in the backdrop.
and less light on face.
Holy hot highlights Batman!!! (Translation: Reduce the output on your key light). Great expression, and the lighting would be great if it wasn't quite so hot. You've got your lights in a good postion, and you've captured a great expression, so you're well on your way, just work on dialling in that exposure (and keep a hairbrush handy too).
