These the Martian for panels 2 and 3 on page 28 of my 2010 comic Martian Debut. I didn’t like how the face turned out, so I redrew it separately and superimposed it over the body in the computer. The chimpanzee was drawn for panel 8 on page 10, but I ultimately used a drawing of a baboon with a baby on its back.
These drawings were collaged together in 2011 on a piece of paper covered in gray paint.
