Wall man

First, this is a good shot. Tonality is great, you capture the context of where this man is jumping, and I find that the high lights on his face bring you to him in the image. While the foreground and background does capture the context, maybe there is a little much context and more drama could be added.

If you feel that you could approach and engage the man, you might consider asking him if you could photograph him jumping. I'd would guess that he would respond favorably, i.e., the collaboration of two artist. That way you could have moved much closer and captured more dramatic moments with your lens pointed upward...
