cave + tiles + gray

[Vipershark]

the problem I see with the column is that it stands out too much from the floor

the way I see it is that it's either

a) what we're seeing is a cutaway of the area, and the bottom of the column is actually INSIDE the floor.
b) the column is in front of the floor, relative to the viewer

I can't tell if it's supposed to be a foreground object or what.
