Nice materials, Ghost, and lovely reflections. The sound supports the whole thing well. When did you decide to pick up Cycles for this 
minoribus, Cycles lends itself to quick play such as this. (Many times I never leave the Material Panel for setup) Not to mention being the render engine for the subject matter. I do them occasionally as a break from that damn project since they take hours.
Not only that but I’ve switched the gallery project from Yafaray to Cycles because of the baking which Yafaray doesn’t have. Render times are looking much better but to be honest so far I’m not any to enthused about the ‘baked look’ Even through it’s mostly flat walls and a textured ceiling. However, that could be my fault and I’m still at it.
