I was fiddling with the illuminated brushes on Procreate and found some that had this nice negative-space effect and thought, I bet I can use that to do something neat, like, to illustrate a character who's moving through a solid object. So who's a character with permeability that's within my tiny range of drawing abilities? Eugene the magical jeep, of course.

He's not quite on model here, so you can tell this is the Eugene of those King Features cartoons they pumped out in the 60s. I tease, but only because I have a lot of opinions about those shorts.

Hey, how about those straight lines I'm deploying in my art now? Pretty slick, huh?
