Could you please follow
this guide? I'd really like to see you spend more time on each map. I'd rather see one high-quality map than 20 medium-quality maps. Not that your maps look bad, but they could be so much more. They still have a late 90's level of detail to them.
I've put the map up on the beta server for play testing and attached a demo of some things that need to be fixed. One thing I forgot to mention in the demo, but eiii pointed it out: the sun doesn't match up with the shadows. I think I made a forum post about which sun angles to use for which sky, or you can just aim your crosshair at the sun and type "angles" at the console. I'd probably just use a different sky entirely, though. With the design you have, most of the map would be in shadow, I think.
