Haha, well I have just been reminded about how many opinions there are on internet forums, and how eager people are to share. And if I exploited Ray by taking a few pictures after talking with the guy for a long time about his life and mine then I guess I'm going straight to hell, because I would do it again without a thought. I have had plenty of embedded photographers follow me around in Afghanistan waiting for me to get shot at, so they could get a good "action shot", but we all see these in Time and call them good photojournalism, and no one complains of exploitation there when the dude is pulling in serious money from the images he gets.(I was taking this for a project for community college class, no money to be made here, and I paid the guy for helping me out) Ray was more than willing to help me out with this project, so much so that it was nearly impossible to get him to stop posing and get back to what he was doing. So, I don't really care about if people think this image is ethical, because I know the entire story behind it, and other people are just wasting their breath/keystrokes in typical internet forum fashion-without knowing what they are talking about.
Back to the picture, thank you to those who have given your thoughts. Under this bridge was a really hard place to not get some random awkward thing in the background protruding into the picture. In addition to that I was right up against the curb with traffic at my back for most of the time, so I had a little box to work in. I don't have a single verticle shot from this position, so I don't think that I could get him all of the way into the frame with what I was working with.
So, composition seems to be the main complaint in this picture. Would cropping it down to just a headshot of him work better, since I did not get this in a vertical frame? I have seen a lot of people say that the picture looks flat. What would help that?(keewp in mind, I've only been going at the whole photography thing for a little over two months, so I'm a noob in every sense of the word.

I know this image wouldn't have conveyed the story in this one picture, but if it was a part of a longer set, what would be your criticisms about the photo if it were cropped down to this?
