Toast King, I really like these textures, and like how they give depth to an otherwise simple hallway/main room. I also like the light you have running along the ceiling, except in the second shot it doesn't really seem like it's casting light... as in the room just seems lit but there aren't many shadows or light contrast. I guess thats the downside of texlighting.

I think you could definitely add some more lighting variety. I like the green light in the first shot (what is that coming from anyway?) and I think other small touches of colored light would look good. I've always liked blue and red for futuristic maps as long as they're used as subtle highlights and not room lights. I love TFC, maybe that's why I love red and blue

I must read the detailing tutorial again =P
Hmm, this will proberly one of my last maps for HL1 because then I will be mapping for source. Yeah! Getting HL2 in 3 days time ^_^

I think it looks cool, but still needs work. you've got nice brushwork, now add small bits of detail for light fixtures and such to make it more interesting. and uhhh.. really long hallways aren't so cool usually.
