It is a nice photo. Presently it has a score of 52.6. There are some picky things: the top of her head blends into the background and her skin is over exposed a little. If it was shot to a raw file, I would reprocess it to bring her skin down a bit and add some fill to get the top of her head back.  Probably I would process it a couple of times to different layers so her hair could be a little lighter and her skin could be darker without changing the background.
