I've been toying with the idea of combining photographed backgrounds with drawn images, and these are the first two attempts to see what it could look like. The background is a little diorama I built for some Star Wars collectables I have, but it never ended up being used that way. I think it works better as a backdrop for these illustrations. If I were to go forward with this idea, I would make architecture of my own design, and not just lift from a galaxy gar, far away.
So the Saturn Squad is a sort of 80's Buddy/Cop movie type thing, but the Buddies/Cops are aliens.
