I have a hard and fast rule for myself whenever drawing Penelope, to drive home the point that her time-split selves have integrated into one being: "Never draw her heads interacting with each other."
Under certain circumstances, though... Even self-imposed rules are dumb and made to be broken.
I went back and forth on whether to actually publish this, because it's just a sketch and most of my work is PG-rated by comparison. But I like it so much (Look! I suck slightly less at drawing feet now!), I thought, eh, why not. I've done enough establishment of my OCs that I can offer a window into moments of their lives like this without shame. ^^
