I've played on this map a few times as a tester and I've enjoyed my time, but I do agree with Wintrius that giving a good idea of the lightning of the overall map will show a distinct difference between just a map with a lot of corners and areas versus one that provides a compelling and distinct appearances. It might be better to set the roofing sooner than later since I feel like what's blocking the grenade throws and angles, as well as giving the map a more grounded feel is important. For example, an upper roof will allow players to bounce a grenade down instead of flinging them way above map. The second bombsite for a 5v5 is also really important in figuring out transfer times in case a team fails the initial push, as well as giving you a better idea of which sites both sides are more likely to win on and prefers pushing.
