Here’s a page from a comic I just finished. I submitted it to an anthology, so you may not see the whole thing in the immediate future. Unfortunately the anthology is in black and white, so I thought I’d put up one of the color pages.
Updated 2020-04-05: This comic originally appeared in C’est Bon Anthology vol. 19 (2012) in black and white. I'm now here including the full color version.
Some of the images are edited from photos sent back by the Curiosity rover on Mars. There are a lot of images at the Jet Propulsion Laboratory website.
