When I do my live streams, I always start by doing a few warm-up images. However when something strikes me as amusing I'm also known to stop what I'm doing and jot out silly images that my muse has dropped into my lap, figuratively-speaking.
In this case, Molly was playing at being "Wasteland Molly" and Genwyn climbed onto her head. I just could help but picture one of those anime-pairings where the heroine has a little companion animal, so I drew a mini-Genwyn perched on Molly's "helmet".
