this I think would have been so much more powerful if the gentleman was not in the background. the look on both of their faces tells me a story. well done good choice of subject matter.
I'm not really sure how this meets the challenge...I would suggest tring to change the lighting. The skin tones are very gray and flat looking... but perhaps it was very difficult to get nice lighting where you were at. Good try though - the focus is good, and the composition fine!
