MarbleDemon - Your map just makes me want to noclip and look at every little detail. (Which I did, it’s gorgeous.)
The whole normal to two-weeks-later transition of your map is fantastic. No complaints at all.
simzboy - I am in love with the sound design. Nothing can finalize the feel of a map like a good audio soundscape.
The particles are a plus too. It gives me a asbestosy sense of no hope.
l33tkill - Clean, pretty, office feel. The 3D skybox is excellent. Only complaint is that the 3D skybox does not surround the playable area itself.
You could see outer-boundaries of the map.
Grenade Man - Great atmosphere, the transition from a dark basement to a bright yard looks really nice.
The map is a little small. (Not as big as the ones mentioned above.)
TurtleeyFP - Looks like something from Half-Life 2 (Fits very well.) The brushwork is very nice, the wrecked walls look like wrecked walls.
The world outside of the level is very blank (Doesn’t look like it was finished.) There is a hole in the concrete where you can fall and die.
