Hi Mary,
I am one who understands poor photo references, having taken many myself.
I think that while this reference isn't ideal, it is very usable. As Allan suggested, removing the white bannister is important. I've done a photoshop rendering with it removed (along with the top of the bannister that peeks out over the top of her head.)
This can be a very strong portrait. The contrast between the soft blur of the little girl (with a few judiciously placed hard edges) and the variations of rough textures behind her can make for a very compelling composition.
I know you'll do a wonderful job with this one.
Good luck.
