I am 100% a game programmer. So all the art work was kinda hard for me and the shape fell into two categories. 1. Blender had a tool for making that shape and 2. I thought it looked semi futuristic and calming.
Not sure honestly! It's probably one of the coolest looking simple shapes.
And like you said, futuristic :]
One tip for your lighting that I noticed: Drag the "Soft Source Radius" of your spotlights way up, until you can't see the harsh point reflections on the walls.
