screenshots too big. just kidding. This map looks excellent. One thing that I always recommend is that if two textures are touching eachother, dont make them even on the wall. Like those red lights on the wall. Make those bulge out as half-cylinders or make them cave into the wall as an inverted half-cylinder. but too keep it from looking too "wolfenstein3d-ish" I always make the surfaces differnt like that (as long as i can afford it in my VIS budget.)

[edit] make your flourescent bulb looking things bulge out from the ceiling. turn the red square light into a pyramid and make your spotlights less defined. (make them overlap and make them bigger because flourescent bulbs do not make a spotlight.)
