y00tz: If you have other players in there, then that's not much to worry about -- the player models are pretty high poly. If wpoly goes up that high, then it's something to worry about.
mik1: Lighting looks pretty good. There's a couple things you need to fix before I can put this up on the server for testing. First off, the filename needs to be all lowercase (linux is case sensitive, so it's easiest to keep everything lower case). Second, you don't have the gamemode set in the worldspawn, so it defaults to CTF mode (or whatever the server is set to) instead of DM. Add "gamemode" "1" to the worldspawn.
I also noticed a few areas where there were slight brush misalignments. Looks like you weren't using the grid (Or used a grid size that was too small). Always use the grid!
Oh, and the one-way transparency in the middle tower looks really weird. I think it would look better if it were just solid.
