The map looks pretty damn good. From what I saw while going through this with Benroads, there's only a few issues that should probably be addressed.

This spot can cover basically the entire map. It's a damn big sightline for snipers. The area that I'm standing here could probably be covered up.

This opening into the spawn area is really open too. A sniper on this balcony could easily abuse it. Covering up the balcony/patio-like area in the last suggestion would probably fix this nicely.

The spawn doesn't have to be that far back. The spawn doors could be moved up to the open doors and the map would still play out just fine.
Other than that, I really like how everything else about the map flows together. You should definitely get some people to play the map and test it before any major changes are made.
