This here post is one that I drew for a class assignment. The Robo is copied (not traced) from a Scott Wegener original and then the background is added by me, inked and water colored.
This one here is made by Scott Wegener
The worm beast is from Empire Strikes back, but see if you can find other pop culture references hiding about.
The original was too big for my scanner so’s I had to take a pic with my dumb phone and upload.
