Great map. Reminiscent of older CS maps during the 1.x - 1.6 era. Don't have any major issues in this map regarding gameplay. When you play this map a few times, rotations will start to feel more natural. It's a big map or atleast you get the illusion it's a big map because of the wide corridors.

A lot of the action tends to shift towards middle. There are a lot of corners to peek when you come from the construction bomb site (forgot if it's A or B) towards middle. I suggest adding a few covers on either side of middle to help peeking for players coming into middle.

Also visibility could be improved in the corridor leading up to the heightend part of middle. See screenshot:
