Man, I never pull my camera out on the subway - gotta get over that fear. You're put in proximity to some very interesting stuff, as this shot attests to. Nice work, DoF heightens the impact, and the person in the distant top left corner glancing over seals the deal.
Interesting study. Like the overall thoughtful feel. I am sure that this would score higher if the persons behind the soldier were not there so that he had a harder edge to emerge from the background.
Very different and unigue - a solid image that is crisp, sharp and properly framed and composed - a technical success in every way. From an artistic standpoint, it has significant impact being richly colored with excellant detail. This image would have worked as a black and white as well. A perfect demonstration of the power of properly controlled light and focus. Well done.
