Damn. Wrong keyboard shortcut, spah sapped mah post.
The map now feels a lot less agoraphobic, if still a bit twisty. (Texturing will probably aid navigation.) I was able to FAN-jump pretty much everywhere it seemed I should.
I've got some screenshots, although I know the answer to some of them might be: "That'll change when I detail the area" or "compiling with better quality settings will fix it".

Weird lighting with stairs, the nostalgia-inducing sign can be stood upon.
Maybe just my computer, but some walls just seem really blotchy.
Compilation settings will probably take care of this automatically later on, but I've been having some trouble of my own in areas with this guy. (Which may or may not be the prop's fault.)
I think this should be the opposite color of the team's base, since these signs are (like in Hydro) usually used to show the team of the same color where to go to find the battle.
The sign says "battlements" but leads to a resupply room. The green texture would be really cool with animation or a water-shader-esque movement to it. (Green light? In a TF2 map? What will Psy or Void think?

)
Top step much brighter.
"My god, it's full of stars!" Rafter seems a bit unsupported.
Maybe it's my computer, or the patterned textures, but in some spots I just see a lot of blotchiness.
"Admit it! You don't even love my intel anymore, you've been seeing another base, haven't you!"
