This map is surely better than your average cp_orange, but still has many issues. First of all, it has no pickups at all! Place small pickups at second, 2 medium pickups at mid, 2 small pickups at tower's outside stairs. Also, I'm not sure why you made underpasses at the tower's entrance walkable, the whole point of them to be crouch-only is to make players who go for health vulnerable. Also, you forgot to add clipping on the spawn hangar roof. It would be actually cool if you would make it surfable. And to add, captime on last is very fast, people play orange not to cap points but mostly for dm, points are just an addition to gameplay.
All in all, its ok map, but still very open and kinda empty, I suggest you should check out some best orange remakes such as cp_orange2_b1(
