i think it was really smart of you to take this at a diagonal.. straight on would have made this less interesting. i like your composition too, it sends a great message to viewers! nice job on the challenge.
I don't quite understand the title, or how this fits the challenge, but I do like the creative angle you used, and might just suggest bringing some of the red tones down a little. Keep shooting! :)
The tilted angle isn't really doing it for me. I like the concept of the shot and respect your feelings towards pollution. The exposure is suffering from sun-haze, adding a reddish tint to the shadows. The clouds do a great job masking the sun, and I like the effect there. I think a straightened horizon would get you a point higher score. Good luck in the challenge!
