The map looks really nice. When playing around on it I thought of some ideas that i think will help the map. (Game-play wise and looks)
1) B seems really hard to take, since the 2 entrances are very small choke points. Maybe add a broken window or wall or just a window in this position to help when the T's do a B push.

2)Just a weird arch that looks small

3)Make Bombsites bigger and add more props/objects in bombsites.
The planting zone for B and A felt very small. Also, both bombsites felt very empty (B more than A) Maybe just add a few crates or something.

4) Just add more props in general. Most places felt fine but in B maybe add another alternative route or just add some more cover for the T's when they exit B main.

Of course this is just my opinion.

Also i really like how there is alot of shortcuts from jumping on things to boost up on stairs. Also alot of wallbangs spots (maybe to many)
