1) The rock ledges in the middle. - Done on purpose, looks GOOD! meant to be hard to see but easy to use.
Looks like misaligned brushes to me.
Plus it looks funny when people walk up those ledges and float in the air. It's also hard for the newbies (the ones who would actually need it) to see, but your call.
2) The thick middle looks alot worse thinner. (to me anyway)
Perhaps figuring out a way to make the edges thicker would help - the tall ones look decent with the thick middle, but because of the angle, the bases are thicker, too.
3) Fading lights are fun 
Unless your video card displays them at 2fps.
But I wouldn't worry to much about it.
4) grass/rock texture in tunnel is suppose to look like muck, might be a better texture for it. Didn't change yet but I'm open to other textures.
Might consider the green water texture, without the warp or water flags set.
Looks good, though. I think the big thing will just be gameplay testing.
Couple other small things:
- The DP crate outside of the yellow base is slightly misaligned.
- The chamber poster that shows up looks a little out of place. I don't really know what to suggest, other than to try to make it look more poster-y or billboardish. Like give it a texture or something, so it doesn't look super clean and computer generated.
- For the windows on the building, you might try making them trans33 and put a black texture behind them or something. They look weird being all white.
I've put the map up on the beta server for testing. Keep up the good work.
Edit: Forgot to mention, with the text file, you could just make that your mapinfo file, too. Just throw [mapinfo] then the appropriate settings at the end and put the .txt file in pball/maps/beta/mapinfo. That way it'll have proper game mode support while in the beta server rotation.
