I took a look at your map:
It's very nice, but there are a few things you should fix.
Seam these Gaps:
The rock here looks strange. I would just use a regular wall texture.
Some other visual stuff:
This railing here is clipping through this crate:
The main part of this platform isn't there. Everytime I go this way I fall through.
The way this CP is help up looks strange. How could 4 thin metal walkways hold this weight up? I would put a round base underneath the CP.
This sign is the wrong color:
From here it seems most of the map is covered by the skybox. This is not necessary. The map will run faster and be better optimized if the skybox only covers up the parts the player will see. For other places that need to be sealed up but the player can't see, use nodraw.
Finally, (this is not detail related), I drew up a little sketch demonstrating how you can make your map's scale a little better. I would create another area right after you exit spawn. Right now you walk out of spawn, go a few yards, and you will see the CP... This isn't good. You should try out something like this:
This map looks pretty nice, and I can't wait to play it soon.
Hope this helps!
