Interesting composition and I think the border works, but the horizon seems tilted to me. The lean of the buildings is distracting. I think the highlights are also a little strong, but you've got good focus & DOF.
there's a big piece of something in the middle of your picture. though i must say it is very nicely exposed perhaps a little fill flash helped, which makes it feel like it is sitting in front of a movie screen with the girl playing on it. so the more i look, the more i really like this technique, i'm just not sure it works for this composition
