I was completely swamped during the voting for this challenge, and didn't have time to make a single comment. In fact, I'm letting my membership lapse for now, as I don't have the time to contribute to the site the way I should.
I like this one a lot. (I'm working to be a professional photographer, of children amongst other things, so this appeals to me.) Candid shots are the best, and this certainly qualifies. The only suggestion I might make is to leave a bit more negative space in there. That is, zoom out a bit on this one. The background is pretty interesting, and while it might overpower the girl, I think it might be worth investigating.
I like this shot, very cute :) I think a little more space on the left side of the frame so her lollipops arent so close to the edge would improve composition.
