I like it and agree with what the others have said. I do have a couple of thoughts that you may want to consider.
First, does the photo need to be in black and white? Some photos are better in B&W and some in color. It looks like christmas lights in the background and I think I can make out a couple of stockings hanging. Unless something is wrong with the white balance I would think this photo would look better with the Christmas colors in the background. Just a thought.
You might also try croping in a way that puts her face off center. It usually works better if the subject is not in the center.
Those are just some suggestions. It is a great photo no matter what you do with it.
