I really like the main t route to a site!
The line of sight between a and b (mid) is too long in my oppinion, maybe double doors do the trick.
I also enjoy the further route to b with the one way drop on the site but i think its a bit too hard to get there because the main enterence is so wide that cts can controll it too easily. Maybe move the enterence a bit closer to the t spawn.
Overall I think this kind of layout has potential but its too ct sided
