I'm sorry if this has been said before... but the only thing i noticed is that the pilars and the gound texture don't "flow" into each other. the edge on the bottom of the pillar is so smooth and straight that it looks like it doesn't go with the floor. know what I mean? I'm a programmer and not a texturist, so I wouldn't know how to change that, but that's just what I noticed...
Other than that: GREAT WORK!!!
looks amazing
