I've added the map to the ev1 beta server and sent you a pm.
Suggestions for improvement:
- Having solid colored tiles everywhere is kind of harsh on the eyes and doesn't look very good. Consider using white tiles with strips of colored tiles. Maybe use tiles of different sizes. Something like this, maybe:
http://www.abgclub.org/resources/internal/file_views/255/1_Locker%20Room%20lockers.jpg -- use a cement texture or something else on the ceiling. Also, align all your brushes on the 32 unit grid so the textures line up properly.
- Dirt for walls/ceilings doesn't look right. Consider using a different texture.
- Barrels are too wide.
- Area with the snow is too bright, and the snow just looks solid white.
- Light textures are misaligned.
- "DP" text on a lot of the boxes is backward.
- Flag texture for elevator platforms and boxes looks bad...
