This has potential to be a really cool shot, you should have tried to get closer, if closer was not possible, at least in front of the trees or more zoom on the factory. I like the long plume of smoke in front of the clear sky.
Great shot, if it just wasn't for that tree in the way of the main subject (just my honest opinion). I would have stepped a little to the left to have the tree be part of your right frame.
The detail and contrast is great in the smoke coming off the stacks. I know its tough to get close to these places, but I think a much tighter shot would be nicer.
I just love the smokestack with the movmement of the smoke/steam. The tree in the foreground helps give it some perspective. I wish that the ground in the foreground wasn't so blacked out. Maybe that's due to the time of day. Or perhaps, convert to black and white and it might be more effective. Still, well composed. 7
