Hey! This was done with LeoCAD and Blender. I downloaded the instructions, grabbed all of the pieces and laid them out in LeoCAD. I then exported them as a huge .obj file into Blender, then assembled the ship from there. Rendered with a transparent background in Cycles, then slapped on top of one of my sky texture pictures from https://naturalhorses.deviantart.com which was motion-blurred in GIMP. Thanks for having a look!
