ct side middle smoke can be easily improvised to be quicker after spawn (just throw in the direction of that large radio mast).
T side is a little bit trickier though. Yours seems ok, but a little time consuming to set up.
The windows at B can be shot through the roof of connector so you dont have to waste a nade to throw smokes through the windows.

Cool stuff though. Nice to see people aready beeing in the lab and finding cool stuff!
