Here are some impressions I got from our test. Aside from the map being over-detailed in general, which you'll have to figure out on your own because excess rarely means anything in particular is overkill.
Visible nodraws around these windows.
I realize it's not meant to ever be seen from this angle, but even from further down I could tell that you've got boards that are thicker than they are wide. I have no idea how you would fix this, but it looks hella weird.
There seems to be no rhyme or reason to the alignment of these brick textures; you've got the floor-level dirt just hanging in mid-air on the left side and then right in the middle of the wall on the right, when it should only ever be at floor level. Also, this area in general has serious arrow spam; I think RED can tell when they come out of spawn that doorways lead outward.
Four problems evident here: The roofs, like many on this map, are too thick and have the wrong texture orientation on the edges. The railing props are spytech and designed for indoors, and look out of place here (and this particular set isn't even aligned properly). And finally there's something up with the lighting on that billboard; I think you're supposed to put a light in front of it or something to accurately simulate the light levels it's meant to have. Or maybe it's just not usually in shadow like that; I dunno.
This room could stand to be a little longer. See that bit of completely blank wall there? I spawned so close to it that it took up almost my entire field of vision.
