Sometimes I think we get too caught up in the aesthetics in our art, and loose sight of the art and message itself. When something can have an impact on your soul, it to me, is a masterpiece, as I feel your composition is. This is wonderful Thank you.
Composition is very good. The focus is a little soft all over. I would have focused on the wall and leave the biker out of focus. Not that he isn't an important part of the photo, but I see him as secondary to the wall and by leaving him blured out a bit, it leaves it to the viewer to see "anyone" at the wall. That, of course, is my humble opinion. David
