I'm just kidding. I'm actually very impressed with this pack. The first two maps seem a little rough, and there's a headbanger poly on the first level (poly 93 is too low when you're coming down the nearby stairs); I think the impression of roughness comes from the lighting, which is not very differentiated from one area to another.

The last three levels, however, are just superb. They make me think of Coriolis Loop, with their nuanced architecture, large horizontal and vertical spaces, and general coolness. Bonus points for your usage of multiple texture sets in some of the levels; it's subtle enough that it doesn't look out of place. Please make more maps!
