If I'm not mistaken, I believe that's the carpet that Ruben (SandmanX) used in his home theater!
I'm a long time voyeur here, but I felt compelled to post to say that I love the work you're doing mcascio and I'm watching with great interest. I particularly like the detail of the renders that you've been doing and the experimentation with different looks.
I'd add a +1 vote for the red. However, it's a conflicted vote for the red, because I'm all for neutral colours... I'm just worried the "tan" is too light, and too much of a contrast to the black.
