Please do more magical girls of these five! I love how you mentioned maybe doing Princess Tutu (my favorite anime) and Sailor Moon. If I could I'd like to recommend a few though you some might not consider them magical girls, the My Little Pony Equestria Girls magical girl set up from the last movie, Kill la Kill, She-Ra, RWBY, and Winx Club or W.I.T.C.H
Okay, so, I can easily blame YOU for my sudden urge to make a Madoka/MLP crossover, WHICH I'M STILL TRYING TO FIGURE OUT!
Seriously, after watching your speedpaint, I suddenly had this idea, and now I can't get it out of my head. Thanks.
