The broad lighting really supports this subject. The hat is perfectly placed to provide a frame for his face....great control of the situation. I can't think of anything that would have made it better....10
OK, I think this is awesome. Some people may nail you for having half of his face in a shadow, and that may have some merit, but that is what I like about the shot. We see him, partly, for who he seems to be, but also have to recognize that we can never fully know somebody. Or maybe I just like the "drama" created by the shadow.
