A third try, this time with more frames and more complicated movement. This is Calliope (Callie to her friends) dancing. I'm not quite sure exactly what kind of dance it is, but it strangely feels like something country-and-western.
Trust me: Moho helps a lot when trying to animate stuff, since it's very good at doing smooth interpolations and extrapolations. Without it, there's no way I could've done this thing. But to use it, you first have to think in terms of vector art, and that's not everybody's cup of tea.
