This should be in the Half-Life 2 section.
Regardless, I haven't tried it but I have some comments just looking at the screens....
Looks cool and probably fun for Sourceforts. Some nice brushwork here that I like, for example the steps and the 3-sided ramp upwards in screen 2. I do see textures in screen #5 that don't line up (on the wall versus the curved ceiling). In fact the ceiling looks a bit weird, too "smooth" for how rough it is, if that makes any sense - is it a displacement or what? You should try the Arch tool, I think it'd look better in this kind of area. I also think it'd be cool if the curved corners around the "blue spawn" door in screen #1 followed the contour of the concrete ground above it (which curves upward and you can see how the pillars are flat on top). I like the texturing in this screen though, how the darker tiles follow the edges walls/vertical brushes. I also like the blue lighting in the background (all the glows along the back wall) as well as how you've given lots of clues that this is the blue side; apart from the glows you have blue text, blue boxes, looks like some blue texture under that grate to the left.. the whole area "feels" blue. I'm sure that helps in-game.
I don't play Sourceforts much, but looks nevertheless like you put some effort into this, especially compared to some of the other 3rd party SF maps out there. Nicely done.
