I don't use references, really. Or guides of any kind, for that matter. My technique for animating (and drawing in general) is 'wing it, ctrl-z if needed, repeat'. Sometimes it turns out good. Other times it comes out unrecognizable. You'll notice that my style changes repeatedly during the course of this animation. Well, that is why. :P I do not recommend animating the way I do.

It's cool to hear you're going to animate Silly Adventures, though! Beat me to it, you did. :D
