That's a pretty skyline, though a bit blurred by the distance. I'm not sure you don't have too much negative space here, though - it sort of overwhlems the photograph. If I scroll until it looks roughly square, it seems a bit stronger as an image.
The neg. space here makes this factory (?) look very small indeed, and hints at pollution with your title (?), so good meeting of the challenge. The factory lights seem just a bit out of focus, where I would think you'd want that clarity here to contrast wtih the fuzzy sky.
