Nice overall effect but I think rough around the edges for sure. I can't bare tex misalignments much and there's some really messed up examples in your map. I know some are meant to attain an effect but i'm talking about the general.
Also, the brushwork is good and bad, some areas you achieve a certain freaky style and others it almost seemed as if you didn't know what to do and ran out of ideas. Like some doorways are awesome and others are just ineffective. Very intricate work though, must be hard.
The waterfall idea is cool, but screw that in multiplayer because that thing is faulty ass. It needs to be easier to get up there, right now it's lank hard (well for me.) You keep on bumping into the cliff. I suggest just flattening the brushwork in that area.
Also add some custom sounds to your level, it adds loads of atmostphere. I like seeing someone else but me use sprites well to glow the window lights. I must say, you have a very good lighting in my opinion.
