Hmmm...k..couple first thoughts: -A lot of highly reflective gold..almost too much for my eyes. See how the pentagram starts to disappear around the edge? Too much reflection picking up the floor. I think I'd kick down the reflection and add a slight brushed metal bump to some of those pieces. Especially since you are going to have a LOT of lights bouncing off all that. -Bump map on the stone walls looks a little strong and a little big. In general I'd try toning down the textures. All that being said I think the design is VERY cool. Look forward to seeing where you go with it.
