I almost submitted a similar shot myself, but in the end, went up going a different direction... good luck.
I'd like to have seen Tehran more clearly. The sky's nice but it should not be the feature here and your subject is too blurred. A really dark, silhouetted skyline would have worked well.
Focus of this picture is more on the sky then the buildings. If I had a magazine called "Urban" this picture would not be one of the first I used. In another contest without the buildings (they look fuzzy to me blurred) the clouds make a wonderful picture on their own.
