This is a great picture. It's a little decieveing at first because you're looking at the city in the distance, but then you focus on the closer building which at first looks to be gigantic. I also find it weird that nothing is coming out of the taller smoke stacks. good luck.
I like the stepping effect of the buildings and the chimneys from left to right. For some reason when I look at this pic I get the feeling that the right side is going to tip over, like when someone is sitting on the end of a bench and tips the whole bench? It isn't negative at all, just the first thing I thought when I saw this. Technically this is very good.
