ok, well right now I'm terminating the render... (this is the same render!)... after 23 hrs 35mins.

C+C please

so far I've got:
Chairs are too boring (+i have to do something about that black artifact on the closest chair's back :headbang
Need something along the back (side table thing with a lamp possibly, maybe a power socket?)
Scene is too boring, maybe make the cloth intersect the chairs and put some chairs in for cool effects???
