Gameday (Impromptu, but whatever) Feedback:
The opening area was nice. Just a bit of combat in it, and then red was defending the first point. That's ideal. No spawn-camping occurred or sentries were irremovable. My only criticism is the flank which seems to just be a space filler. But I'm okay with that as long as the area is pretty, it might be good for when red sets up 5 sentries just outside spawn. Also I would like to be able to crouch-jump onto the low ledge on the left (from blu's perspective) off of the crate as any class.
The first point could use a tad bit of work. The hole in the wall isn't clipped in the best way possible. It might be clipped, but the lowest area seems like you should be able to just walk through without a jump. The little area behind the medium health and ammo, towards the deathpit. I only ever went there as a cloaked spy, so consider making this area suit these needs. Change the healthpack to an ammopack, and consider increasing the size. On the ledge near the hole on the first point, it would make sentries more vulnerable if you could crouch-jump onto it from the ground on red's side.
The area between the two points was a bit of a trade-off. The little ledge that runs around the building is weird and really annoying if spies take. The big side flank is long, and doesn't look like a good route in general. You cannot escape from it, and it tends to expose you to extra fire. The other tiny drop-down would be great if you could jump onto the pipe there. You should clip the ramp above the dirt so it isn't so easy to fall off the sides.
With regard to the last point there are the most problems (if that makes sense). The door near red's spawn should stop opening after the first point is captured, so they don't have such easy access to the flanks. You could just shut down that part of red's spawn and let blu go through that door themselves after capping the point. The stairway on the right flank (from blu's perspective) needs to have a fence underneath it or something.
On a final not you need to fix your lighting. I did really enjoy the first point, and though that the second point had good potential. I look forward to seeing this updated. Good luck.
