#2 I really like. It breaks a lot of "rules" but it drew me in.
The one with the pipes I would crop down some and take out the overhead light. I might even do it in black and white.
The last two don't do a lot for me. I like the concept of the hallway, but the blurred man just throws me. I get that it was intentional, and it seems like you were going for a sense of urgency, it just distracts me. The tree between the birds looks OOF. It's a neat snapshot, but that's about it.
Two and three are my favorites.
