Not a bad map, Second Picture the middle of the area is empty, think of something GOOD to add, and the last picture, the lights seem weird, i never knew that light posts where blue, change it to more white than blue (brighter), and the yello, make it brighter...other stuff are ok, keep us informed of newer updates.

Ahem...

cough cough

Any other critques?

it's not possible to apply textures to skybox brushes.... i meant
simply the map uses different textures as skybox cubic maps, different
from the in-game ones

Did you apply the different sky textures to your skybox? You're meant to just use tools/skybox texture silly.
