I think this photo has a lot of potential. The focus is good, as is the subject matter and composition, but I do not think the sepia tone does it justice. It is too monotonal.
I love the grainyness of the image and the color choice. BOth I suspect were intentional. It brings a sense of forlorn existence and poverty that you have successfully captured here.
I want this to win the challenge. It is simple and brilliant, and whether intended or not, the heavy amount of noise adds a texture appropriate to the theme.
