Well, I think it could deal with being just a bit brighter. Even on a couple good monitors I had to strain my eyes to see the subject. I think the scene was excellently executed, and the pastel softness of the shot really adds to it, but it could certainly come up a bit and still retain that feeling. The other thing is that tree. Someone above this post said they like how it framed the shot, but I disagree. Most of the shot is clean, soft, sweeping lines, which adds a spaciousness to the photo, but the tree just distracts from it. I might have cropped it out.
Nice work
Edit: Wow, OK. I didn't realize just how bad the backlighting was in here when I posted that. It's plenty bright when viewed in a room with controlled lighting!
