Wanna give some simple feedback
1) You have a leak here; it makes your map be completely rendered from everywhere and makes bad lighting in some places. Resize this brush vertically and horizontally. You can check for leaks by going "Map" -> "Load Pointfile" in Hammer, it'll show you where one of the leaks is with the red lines
2) If you want people not to stand here, you can just use toolsclip or toolsplayerclip brush textures. If you also don't want people to shoot there (exactly what this blockbullets texture helps with), just use skybox texture for easy optimization. Also raise these brushes so people can't stand on them
3) For whatever reason, Blu has closer spawns than Red
4) Blu doors are not renamed and they function literally exactly like red doors. Also, both doors for each team have the exact same name; that'll make them open even if you'd want only one of them
5) All doors on the map have "Touch Opens" flag, that makes them opened untill the end of time by anyone who just toches the door. This is something that for some reason is enabled for every newly created func_door
6) I would recommend to make this vent shorter (like on the image) to make it feel more impactful and important
7) You have these major sniper sightlines that go through the whole map
