Give some comments on what is not right, is the lighting ok…what about the material. Thanks.
Nice image. Tell us about technique you’ve used - I mean Photon Mapping or Irradiance, what kind of lights, etc.
light
The only thing i use is plenty of photometric lights…look at a similar post called 120 ies 3 hours to render…most people say im crazy…but i usually follow the lighting design for a room. if the design has 200 lights…then ill put the same amount to their respective location…that way we can really simulate how its goin to be in real life..the use of ies is important…u can download them from erco.com
ill post my settings after a few more c&c.
I like the overall image. The materials seems fine to me as well.
And here some crits:
-The wood texture of the ceilling could be of a higher resolution, but maybe it just needs a higher sub divis amount for the glossy.
> Just a minor issue, by the way… 
- Another thing that disturbes me is that strange brown face between the floor and the white pedestal. Is that a step to the platform?
cheers

what duffuse multiplier you used for ies? of course if you used photon mapping after all.
and please, share your settings
