Now had better inspection on your map, and my results...
I don't see any faults, no leaks or glitches. Works like perfect. Didn't get stuck or similar.
With doors, this gives bit more chances to get close enough, especially alien main base won't get raped that easily.
And with more decoration, this map certainly looks better. Improved lighting also creates good atmosphere on the map.
Now, in my opinion, this would be good to put on even official servers.
Only thing that needs to resolve fix that skybox. Looks bit sick on edges.

And see does this suck on gameplay or not.
