Well from the screenshots it looks a lot better then the version you originally showed me.
I will edit when i play the map.

EDIT: I find this map is well constructed. I personally like the texture choices, and there are only 2 problems I found. One is that flags can be passed through the grating, as was already stated. The other is that you can get back up to the spawn rooms with the ramp/jump things. This sorta destroys the purpose of a spawn room.
Anyway, your call on the spawn room, though it does work how it is now.
