good clear shot, not sure what he is doing or why. would like to see him in a different colour t-shirt - this one doesn't match and yet doesn't contrast with the wall.meets challenge
I kind of like the orange on orange this image has, helps draw attention to the boy more. I'm not sure about his expression though, although I'm sure you didn't have much of a choice on his expression. His black hair really draws you out of the center nicely.
Interesting monochromatic theme. You rarely see that much orange. It suits the challenge. HIs expression seems a tad strained. I'd up the tonality a bit by adjusting curves. Overall - provoking and different.
