For the density. It would remain almost constent near the axis of 
rotation, then increase somewhat faster as you get nearer to the outer 
surface. I'd go for proportional to the square of the radius. At least, 
it looks reasonable to me. Use a cylindrical pattern:
density{cylindrical poly_wave 0.5 density_map{[0 1][1,0.3]}}

Your cloudy "sky" looks out of place here. A large transparent area, 
while good to get some natural light, is a great structural weakness, 
not to mention that that area is lost from the ocupancy potential of the 
station. If it's just a decoration for the inabitants, it's even worst. 
Also, as the illumination seems to come from that bright axial beam, it 
should be constant everywhere.

If you want your buildings to taper toward the top, I suggest using 
prisms instead of simple boxes. But, unless a building is particularly 
broad, there is no real reason that they should'nt have a constant width.
