CRITICAL ERROR, sign of noob mapper:
SOLID_VPHYSICS static prop with no vphysics model! (models/props_foliage/tree_pine01.mdl)
Looks pretty good, there's some problems with the reflective floor in both of the bases where the reflections abruptly cut off. Pretty sure this is caused by misaligned lightmaps, something to double check down the road. The reflections look kind of bad anyways, maybe just pick a floor texture that doesn't shine.
I really don't like the cave that goes underground into the bases, it feels like too much of a run to do that little u-turn. Nothing wrong with it thematically, it just feels like an arbitrary mapper decision. I don't know how much leeway you have for adjusting that in terms of map balance but making it shorter would probably help.
CP 2 looks better with it centered on the control point.
