I've seen a pic by The Fear (not in DevArt) in which he does far worse to Bart & Lisa ! Mutilation ,far worse !
(I love how Lisa's judiciously-placed left-foot stops this from being an up-skirt pic. Maybe you could make an altered version...)
I'm so bad at drawing them
Lisa's feet XD
By the way, I've noticed that Lisa's left foot looks like a right one, same for Bart's one his right looks like a left one, because of the big toe on the right who reminds me of a Big toe
AWESOME JOB, Mysticalpha!!! I'm very appreciative of your fantastic work.
