I see quite a few jaggies, especially along his shoulders adn the rail above. Seems like the picture might have been fuzzy and then was oversharpened to compensate. His hat and shirt both seem overexposed to me.
Although a good composition, but the image is little out of focus. The brightness is on the higher side and contrast does'nt seem right. Maybe a fill-in-flash would have removed the dark shadows from the image and have made it much better.
DOF ... what happened to it.... considering that you wanted to highlight the background. Overall the picture is little weak in clarity and focus but I guess a B/W / sephia tone of the same image would have looked better.
