You have succeeded in creating a unique vision! Very nice work. As we discussed, the foor texture is too low resolution - perhap use a ZBrush texture for this a 1024 minimun. The shadows need to be thrown - they don't have to be dark, but they would establish where the floor is and connect the colums to the floor. The circular objects on the floor are not quite working - a new texture or shadow might help. You also might want to try an alternate texture on the canopy, or else put some decor on the front canopy.
My favorite part are the designs in the back. I like the graphic style!
