Toroid Mothership
This was a really simple render I made in about 1 hour. The scene consists of a default torus mesh with a spaceship-details texture applied to it, some small spaceships with the same texture as the torus, a few volumetric clouds that were downloaded from the internet, and a large ocean made using the Alt-Tab Ocean add-on for blender.
There is also a kuwahara filter added in the compositing tab which makes the final render look like it was painted.
