Here a render using one of my Terragen canyon scene as a HDRI environment in Blender and a free 3D StarWars Tie Interceptor object (released under licence Creative Commons Zero 1.0 – credits to Daniel Andersson)
Original Terragen 360° picture was 3000×1500 pixels and looks like :
For this picture, I used a free (for non commercial pictures) R2D2 model found on blendswap website.
I used also my desert scene (available in my store) where I removed all vegetations, and added a second sun in the sky with a low strength.
I changed also camera FOV and added a depth of field effect.
