Well, I'd say it's pretty good. Let's see -- what needed to be fixed? The ladder fort thing on the blue base. You need to edit or create a new batch file to use -scale 2 (-extra and -chop32 will make it look better as well). I'd use "forcejail" "1" in the worldspawn. Do you want me to create a worldspawn option that will prevent teammates from killing each other in jail?
Another thing that kinda bugs me is that some of the crates in the high center area (around the jail buttons) are misaligned. I guess it isn't as obvious where the borders are on those. I might just edit them so that they look the same regardless of alignment.
Oh, yeah, also minor, but the lights over the flag, and I think one light on the high path are one texel off. Not a biggie, but might as well fix it. You might use a different colored light for the blue base, too. Yellow doesn't light blue very well.
I'm going to see if I can modify the green water .wal so it looks like it's emitting more of a green color than brown.
I think that's pretty much it.
