I think that this image could be better with a tad of shadows/highlights adjustment and the crop is a bit too tight on the top of the head, methinks ... but ... it is a great shot other than those two items IMO.
Here's my two cents. :)
I'm not sure having the girl in blue was a good idea... blue is a sort of "cold" color, and it makes this picture feel a little chilly, which doesn't quite work with the "warm" yellow-green background. But otherwise, this is pretty cool! Good shot!
