Good music.
The poly count is a wee to high, maybe make those pillars simpler if it's not too much trouble. I liked the lighting, very realistic actually, but it's boring, put a small grating over the hole in the ceiling to get some nice shadow effects. <<seriously do this.
The ammo was a bit excessive. I thought the size was fine for the layout. The waterfall's didn't match the color of the smoke effects, maybe you could make those special lit to match...looked very nice really.
