I tested the map yesterday and I think some parts of it need some changes/rework for a sake of a better gameplay and map balance. Bombsite A and Mid area heavily favor the CT side in its current state. I will try to explain you step by step(with screenshots) what I mean.

LONG A
CTs have a clear view to almost the whole lower mid area. Ts cannot even aproach to the building or ramp without being in danger. So it would be good to modify the choke point by closing the small door(or put there a red squeaky door like on the other side of A site near CT spawn, so CTs will have to blow it off with an HE if they want a bigger angle to hold towards lower mid) allowing Ts to jump up on the side of the ramp and get closer to the building without being exposed and also to give less info away about their position or set up.

MID
Once again, CTs have a very good view to mid and lower mid and they can easily counter any T push towards mid(A short or main, I am not familiar with callouts yet) or A site in general. I would suggest to close off the entire upper mid(CT side) with a metal barrier and make a new entry by replacing the door right next to it with a squeaky one.

(I know that this change might seem radical to you and something totally different from your original vision of the layout, but I believe it would be beneficial for the map after all.)
It will still allow CTs to have a view/peek from over the metal barrier if they jump up on the yellow poles behind it or even jump over the barrier, but Ts will have less angles to worry about. Also Ts will be able to flank or rotate to/from B easier through the new T shaped (connector?).

Personally I would also remove a big part of the pavement, leaving just a short piece behind the building and move the pole further as well(behind cover).

LOWER MID/MAIN WAREHOUSE
It would be good to have the windows open for throwing nades like on the other side.
