Interesting shots there.
I like the second one personally. It kind of has a bit of a tunnel effect in what feels like a very desolate place. Makes me want to get out of there!
The first shot is a little busy for my taste. I would also prefer the brick in the foreground to be a little brighter/crisper. It feels to me like that is the most interesting part of the capture, yet your brightest, largest object is a slightly out of focus pillar in the center of the room.
