There was some heavy editing here (I'm guessing tone mapping) and lighting really doesn't feel natural. There also seems to be halos around the pipes and trees.

Not so interesting composition either, a bit too static. And it doesn't feel complex at all, just a bit weird.

Solid overall submission. I love the tones.

I'm not ever sure what this is, so that makes it complex. I wish the composition were able to s how a bit more of the side of this place. Looks like an amazing 'thing!'

I like this,and it really makes me curious about the structure's use.
What caused the shadows at either end of the photo?
