I didn't want to clutter the upload thread, so here's a couple of things I noticed on the maps that have already been posted.
First of all, I really like the train station, the only thing I regret is the inability to jump straight down from the spawn points. That's the first thing you want to do when you are there, and the railing is low enough to give the impression that you can - when in fact, the area is clipped. Maybe a couple of boards with arrows would make it clearer. Other than that, it's really well done, the detailing (offices, painting supplies under the stairs...) is awesome. Maybe the skybox stuff is overkill - isn't the mountain vista gorgeous enough? One can say that it makes it friendlier with other skies, though.
The boiler room is great too, the ambiance is just perfect with the steam and all. However, there is a quite obvious gap between the grate and the wall (I assume you can re-upload it before the end of the month). There is also a slight lighting issue (see screen 1), although I'm not sure there's much you can do about it. Lastly, the two-part spawn room in 2fort-style is a refreshing touch, we don't see many of these around and it's nice to have one in this contest.
Snipergen's spawn room is of simpler design, but still efficient. I like the mix of natural and artificial light. I noticed a couple of glitches, however - see screen 2 (also, the vents on the left of the exit aren't attached to the wall). It's only a couple of modifications, though, so you should have time to make them until the end of the month
