P.S. I love drawing Mrs. Hanamura so much you guys, seriously. Seriously. IF ONLY I COULD GET OVER THIS GODDAMN "OH LOOK, EVERYTHING YOU TOUCH TURNS TO SHIT" BLOCK I MIGHT EVEN BE ABLE TO DRAW HER WELL. :/
Also, should anyone want to join me while I attempt to Pchat away this horrid blockishness, I'm there for a bit!
