Here is an internal render (2.58) of an existing craft based on Cold War Soviet tech. I’m calling this one finished, but I may do a small animation further on down the line.

Also, here’s a couple of WIP images.
The Earth model is from a tutorial by BlenderGuru, and the spacecraft is comped together with it in Photoshop. Mainly to keep render times down and give me more control over placement, lighting etc.
