I like the look--would be great to have an extended experience in this battle-damaged location.

Euh.. i agree with batcature, many things to re-work.. well, thumb up !

I believe you REALLY should work on this, this is not the first time I've seen a map of yours.
- Try to use instances in order to make doorframes, free-standing doors look horrible.
- The neurotoxin pipes are going in to the wall, so try to 'hide' the fact that they're just static props by making a fake tube exit.
- Please do something about your compiler errors, brightness maps like this are just crappy.
- Try not to put random assets everywhere
- The fan rotates, but it just floats in the air
- There is no consistency in this fake 'testchamber'
- there is a random fizzler field in a broken wall, try to make it invisible or at least less obvious
