I really like it, and see that you have captured that eastern european stark effect.
I agree with Lucid Ninja and think that indeed it does look "minature" for some reason? I wonder is it the depth of field you added in Photoshop that makes it that way?
As to the floor I like it like it is, for me the floor is wet because every so often it gets 'flushed' using the device(s) on the wall, in fact I would add a bit of "wet" to the bottoms of the walls... But it's not mine so... Great work - would love to see the animation.
