This is part of a Lux community project which actually features the aquarium tank and its inhabitants. This cafe scene is designed to be a background for other pics so its "footprint" must be light.

400k non-subd polys and 45% of those are the fish decorations hanging from the ceiling and the crude people for scale.

Sadly, little came of the project, but I liked how the cafe came out with so little to work with.
