Great job with most of the alignments, clip bushes, etc.
I agree with scars, the terrain is good, but some places are too empty. And maybe you should choose a third main texture, that the map doesn't look the same everywhere.
In my opinion there're too many plants for an underground world. It doesn't really fit the theme and the ground texture of this map. I'd replace all of them with some other stuff. It's not necessary to have func_models in all maps. Just let it be if there's no reason for them.
Delete "model" "models/plants/bigleaf2.md2" from the worldspawn.
You could also add "maxteams" "2" to the worldspawn.
Maybe a lower count second flag would improve the gameplay, because it's a lot faster to grab the front flag than to grab the main flag.
Add "angle" "#" to your player spawns, that players don't look in front of a wall after spawning!Finally a few screenshots...
Red: Misaligned. There're some more wood brushes like this. Make sure all wood textures have the surface properties S=0 and T=0 to fix this.

Red: Misaligned. Make sure all rock textures have the surface properties S=0 and T=0 to fix this.
