Its a very nice job, I specially liked the ceiling. Very nice job there.
I would double check the black marble texture size, looks a bit too big, and lower a bit the brightness of the stuff in the table (might be easyer in postproduction)
Also are the cabinets (sorry for my bad english not sure how to call them) supposed to have light inside them? Looks like they have, if they are supposed to have try to make it a bit more yellowish to match the rest of artificial lighting
