Hi jewel.
I'm inclined to agree with Adrian.
The foreground is too bright and vivid, and as a result is too distracting. Also, the fact that your neice's head and hands (the focal points of the picture) haven't filled the frame, add to the distraction.
If you had filled the frame then the foreground wouldn't have been so distracting.
Nevertheless a good, well timed and natural looking pose. It seems well lit to me, not too many harsh shadows, and nothing overblown and too bright on the face.
The only other thing I would suggest is her denim sleeve seems to be protruding a little too much, almost to the point of distraction, as it has broken up the view of her face, a 'rejiggle' of the arm and sleeve at the time of shooting would have prevented that
Cute kid by the way
