The man in the photo needs a tighter crop. It would help to get rid of the washed out sky and top parts of the photo. Second, it would help to make the gentleman more presumably the main focal point of the photo. As it stands know he is almost close enough to make the photo about him or almost far away to make the scenery the subject matter with a man in it to create a mood, a sense of human interaction. I would say crop or if you get a chance to shot again take photo closer to him or further away from him.
The tones look good and I like the concrete posts holding the fence and the front window with the grafffite.
