This is a great idea. At first the blue seeems like a frame - then you see the subtle texture and the elbow over the edge and realize it in real. Nice way to include shape, make it your subject while having aperson as a subject. I like the way the background too. 9
Nice use of shape as a frame, rather than the center of the photo. It takes enough of the space to become a subject, while the portrait and the building in the background form an interesting picture in themselves. Was the circular piece created for the photo? Was it there for some other purpose? Or was it added in post production (though the way the kid's arm is resting on it makes that seem unlikely).
