LMcLean, thanks for your comments. I will certainly give some of them a try. I agree about the blue being to strong. But, it does provide a sense of scale for the room. I'll try toning it down. The floor does need work...I'm thinking I'll use some worn chevron stripes and some German warnings on it as well.

I'll try w/out the space frame shadows, but I think they are helpful in adding some necessary detail to a mundane surface.

best,
Chipp
