Back to comment: A lovely little girl but sorry but this is more of a candid photo than a portrait in my opinion. As for the image itself, the focus around the girl's fore arm appears to be a little soft. Did you remember to sharpen the image after downsizing for the challenge?
Revisititng this image again: On my computer at home, this image looks a lot sharper than on the computer I used to vote. Her eyes look very nice and I'm bumping your score to correct my mistake. The only part of this image that doesn't work for me is the negative space on the right. I realize you needed to put it there to meet the challenge but it doesn't really add any value to the image itself. A tighter crop on the girl may help.
