You need to change the spawn angles to the direction of the closest exit. Spawning facing a wall is annoying.
Also on that note you have enough space in the spawning area to make spawns 64-ish units apart, this allows for smooth spawning
You need to include an info_intermission, I think a view of the statue place would be nice
Don't forget to naturalise a lot of your staircases, some are too steep
I think the stairs should be like this, infact most should be.
I think the stairs would work better like this, and I think it might work out better to lower the elevation of this platform to the height that the yellow lines go to.
Also don't forget about what I said about the rail.
the flagpole grassshould be like this
Stairs, and don't forget about removing autoclip on those models and the size too.
I think you should raise the dip here like the yellow suggests, also I think you can remove the stairs inside and make the stairs outside like this and just have 1 set of stairs instead of 3
