Had a quick look through, got a few things to say:
Should make the area aroudn the rocket either a fall to your death area, or cover it up a bit more. It looks wierd seeing someone stood on nothing.
These concrete blocks are overlapping on their corners. Split them up a bit so there not intersecting
This rocky area right next to A may be a good sentry spot, but I got stuck in the middle of the rock bunch, might want to playerclip them (Where I am aiming)
And outside of RED spawn on the wall of pipes, you need another pillar on the end so the end of this prop is covered.
Other than that, from what I saw, the map itself looks great. Needs details in a lot of places and possibly scaling down in areas too. We'll see what happens during gameday though.
