A naked version of the girl from the unfinished jam comic. There were no naked versions of her in the comic itself. I’ve found that it’s easier to give a character the proper shape and mass if I draw the character without clothes first. The clothes then have a form to go around, to hang upon, to bend with.
I don’t know who the woman in the upper left is. I don’t remember such a character being in the story but I could have forgotten.
