The light seems unbalanced, and while the wall is framing the greenery I find that the girl wants to be the focus of the shot (and therefore not framed). Hope that made sense. :)
I think you missed the idea of the challenge. The idea was that the foreground framed the main subject of the photo. Although your model and the wall is framing the bushes in the background, I don't think that was meant to be the main subject. The lighing and color depth could also be improved on.
emily is pretty and this is a lovely shot BUT...while it's a great shot, I can't see a frame in the foreground framing what's in the background...or is it just me? sorry
