I love the black and white/sepia thing. I love pictures from cities in general, but the colors you use makes it really cool and bring forward the atmosphere. (Excuse my bad english)
Oh my God, it is sad to see such a scene, so much pollution. I like the way you mixed sepia with black and white, gives a focus to the urban problem you are presenting. Really nice photo and a good showcase of the worst of our cities development.
image with great meaning..smoke emitting and people watching . what else to say.. nice capture of scene!
btw, you should send the foto to the press and show the pollution harm done.
