I think that in this case it would have benefited you more to have a person model in shabby clothes, preferably a child, standing in the doorway. Someone who innocently doesn't know any different between their life and yours. I think the monotone works, but maybe something with higher contrast. Just a thought.
There seems to be a confusion between Poverty and decay in this challenge, although related they are not the same.This is a great image and I like the presentation of it but for me it doesnt say poverty,.however I have taken a broad view of the subject and rated it reasonably high {for me}
This is great picture of some old buildings. What would make the connection even stronger to the challenge would be some evidence that there are people living here. Clothes on a clothes line, a person in the doorway, etc.
Excellent shot, one of the best in the challenge IMO. If you ever get the opportunity to reshoot this, I think it would probably look great at night with startrails above it.
