I'm always impressed by May's and Momo's body language and how it informs their character. May is nearly always arms akimbo, slouching, relaxed, wide-stanced. Momo nearly always has hands or arms folded, limbs close in, careful posture. You could read a comic without word balloons and get their relationship. In fact, I'd like to see a week of wordless May and Momo comics. I think there's a lot of potential there.
