Very nice, as the other commentors said, she's extremely cute. I like the scene, it fits the challenge, and I don't mind the border (although the border didn't add anything to the photo either).
Some other things I notice: The top of her head is cut off. Sometimes this is ok, but in this case is more looks like you just missed the shot you were looking for. Her arms are a little awkward, and the subject being dead center give the feel of "snapshot" rather than "candid moment". Perhaps taking a series of photos in a row would have helped you get a slightly better overall composition.
