looks really good, but as strat said the lighting needs work.. with that big dome roof, you really need shadows up there, so that you cant see the top of the ceiling. also, another thing that would look cool there, if you darkened it up a whole lot, would be a black sky, but at some point with that hole in the roof be able to see a full moon ;D and have like a patch of white light on the floor that would look so cool anyway... keep up the good work
