This was done in Krita. For some reason, no matter how I adjusted my brush settings, I struggled quite a bit to get the tips of the line to come to a point. I will say that just this one doodle really taught me a bunch of things. I'm not sure I'll jump right into my next piece, but I'm feeling more confident to do more.
The diaper print was modeled after cars Luvs from the early 1990s. I remember wearing these myself. 90s kids unite!
