I continue to work on this - I have adjusted the design so the agricultural toruses taper towards the centre, this to allow sunlight to reach them all.
The large rear ring mirror serves to direct light into the rear agricultural sections (For accuracy the light should come directly along the axis, but that makes the features hard to see).
I also added some trees to the inside of the spherical habitat, and cleaned up the textures a lot.
The Bernal Sphere is a 'small' habitat , about a kilometre long. It is considered a fairly efficient use of mass, as the agricultural toruses double as radiation shielding from solar storms. The vanes are not solar panels, but are for cooling purposes.
Note the small x33 style shuttle approaching to dock with the station.
This is a fuill 1080p animation, and I hope you will watch it full size!
Everything is CGI and done in Lightwave 3d.
