Alright nine. You asked for pictures, so here they are. Feel free to ignore as much of this as you want, since its just thoughts flowing though my head.
Possibly push that area back in, or better yet, add some walls to the sides, something where it comes out, but the top corner is clipped. This will make this sg spot protected from the track, and limit where it can shoot. It should also still be weak from a demo shooting over or someone shooting from the windows of that red building to the right.
Same thing, add a small wall here. Several people tried to build up there, but its too easy to out range it along the back wall. If you add this half wall, it will be protected from that side, but at the cost of only being able to cover the very last part of the track. A soldier firing rockets from the windows across the way, or in the doorway of the first picture, should be able to take it out.
Some people mentioned this today, about how the blu spawn exits away from the point (even though there is a big sign). To fight this, move the entrance to either of the spots numbered 1 or 2. I'm not sure what kind of vertical room you have there, so if you went with 2, you might want to shorten up the raised area there.
A rock or something here to provide some more cover would be nice.
Another half wall, protects the spawn from being spawned.

Alright, these last 2 are the bigger changes that I was just thinking about, so idk what you're thoughts are, or how they would change gameplay.
Maybe add another rocky area here on the left, with some kind of path from the area on the right (wood planks?) A few rocks for some cover. Maybe a medium health/ammo. This would also create an sg spot at the bottom, though it wouldn't be very good because someone can shoot down. Possibly a route from the window, though that might make the area too abused by red. Yeah, probably scratch that.
Add a second layer here? Thats all the blu, a new floor (much like badwater, maybe even a little too much). Pillars to support it, rather than solid walls. A new window so blu can get up there. Yellow would be crates or something else to protect line of sight and give blu some cover. Green is another half wall on top of the new area. The red is an idea for some kind of new building up there, since it would be really open. Probably sniper windows. I forgot to draw some kind of access path, maybe on that side, or just in front of where I drew the blu (so it would be between that and the track).
My final suggestion is to do something about the red shortcut door, since you still spawn facing that direction until blu captures the 3rd point. Maybe have one of the no entry hands.
