When you have to animate a character and draw her hundreds of times, you want to come up with a design that's actually enjoyable to draw. You try to use as much of the body's expressive power as possible. That's why artists have traditionally preferred to draw the nude as opposed to the clothed figure, because you want to get the maximum amount of emotional expressiveness in your figure. I also wasn't sure if viewers would be interested in the kinds of stories I was trying to tell. But I did know that if I could at least [draw viewers] based on her being fun to look at, then people would watch.
