Apologies for not getting any proper testing done for a while, but hopefully with i63 done and dusted and season 31 coming up, people should be more motivated to test out your map. Here are some minor things I spotted while running around on the map:
You can jump through the windows on RED side, but not on BLU. I think you should definitely be able to use the windows, and I also think it should just be one big window since the separation of the windows makes it really easy to mess up jumps through them, which is frustrating.

These two exits to the slanted roof aren't properly mirrored, and you can sit on top of the window frame. This is actually a pretty big deal since the RED window spot is a great spam spot for a soldier while the BLU side is very difficult to make use of. If you want people to be able to sit on top of these windows you should make that more visually apparent.

And finally, I think these entrances to the room near middle are a bit too tight. The room is cramped enough as it is already.
