Your composition and lighting are excellent. It might have been more impactful without the legs in the upper left, although they do provide some context. You have definitely captured the sadness here.
I really like this photo. Only improvement might have been to have the walker-by out of the picture but on the other hand maybe that helps tell the story. Maybe a slightly lower angle would help as well. But I really like it. 10
Very poignant; it conveys so much that I wonder if it is even right to comment on technical aspects. But I will :P, I wish the man's body were not cropped off from the right and bottom. A little more space on the bottom would also add some context...About the passerby I'm not so sure. I started out thinking that he would be better off missing, but on second thoughts, I think he adds to the neglected, passed-by
feel of the subject. Wonder what this looks like in B/W. 7.
The implied line running from the blurry shoe through the seam in the pavement and on through the wrinkles in his sleeves, though probably unintentional, might have been used creatively to your advantage.
Portrays more than just the man... I like the person walking by quickly behind him. I imagine that being ignored is just one of the common occurances in this man's life. Well caught.
