I really like the shot, the lines, the angles, and the shadows are really nice. The only thing I found distracting was the two people in the bottom right corner--I think it would have been more powerful if they were cropped out. That shadow is so strong and sure helps this image be powerful.
nice lines and composiiton. great contrast. Love how you have the other people there in the corner in the shadows to kind of contrast the person that is alone.
