I think the camera likes this little girl, but honestly, if this were one of my shots I would likely bin it. She deserves the time and location to take a good photo.
Even with the tight crop, the plastic bag is just annoying to me. Add to that the effects of the background, I would chalk it up as an experiment that went south.
I'd try another day. (and please, little girls this age need to have the utmost consideration and discretion of pose, especially if they are to be posted on the internet. let common sense rule.)
