Mine's the MC, too, Calliope. The thing is, I love super hero comics, so I really enjoy drawing muscular bodies, which doesn't really go well with clothing. That was a big part of the reson for her "design": I like drawing muscles
As for the least favorite right now (which I know wasn't the point of the thread, but I feel like venting a little) would be the deuteragonist, Angelo, who's just way to difficult to draw
His facial features are waaay to precise (otherwise he looks really funky) and his design is way more complex. Although I prefer drawing male characters to female characters usually
