I like it! Others might be more critical of the crop, which is tight to her back and the top of her head, but it works for me.
As for lighting, I'd like to see a little separation between the front of her dress and the background, but that's a minor nit.
She looks comfortable in the pose and that goes a long way to making an image work.
Agree with Bryan for the most part. The two nits he pointed out are perhaps larger nits IMO.
I do like the overall photo, however. Good work.
