Well I like the idbase textures too, but ogro's texture-set is a bit darker grimmer.
This shots show more or less one room, so I don't think it's repeating. Here is another (with brown ogro textures)

The large red lightpanel in the first shot is the back site of the computer. Already put a pulsing light there, looks a lot better.
The three pipes are made in an obvious manner, does it look bad?
Thanks for some nice ideas and feedback :)
