Is there any reason for the T spawn to be in an enclosed space?
It somehow looks tacked-on to me and feels like a dead-end that would have no use after spawning.
It's kind of hard to have an idea of what the place is going to be as it seems to be the least detailed location of the map, but I'm thinking extending the area it is connected to further back and move the spawns there would play and feel better, while keeping the current timings.
It's probably just personal preference but my opinion was that having a more open space like a garden would compliment the building in front of it (I guess it will be an hotel?) better.
And like blackdog said, I like what I'm seeing in this greybox already
