I've played on that server (as seen in one of the discussions) and this is one of the best community maps I've played on. However, maybe you should make the buildings able to be walked on, and maybe stairways to a couple of them (for snipers, soldiers, engineers, demomen) because it's pointless to rocket jump or stickyjump and there aren't many good places to snipe and build. Just a suggestion. I think it's great either way!
