It's a sad picture. The left side of the shot seems serene, beautiful. The paper mill makes shows of an industrial time. It's a fight between the good and bad, the beautiful and the ugly. A wonderful story and beautiful shot.
The composition is great. The sky looks wonderfully moody and the balance between the sky and the foreground in terms of exposure is really quite good. The sky might be blown a bit towards the top, but understandably so what a tricky light situation.
