Once I have the motion exactly how I want it, I can start to worry about filling in the details.
Ren and Stimpy animator John Kricfalusi has lots of great advice for budding animators, and makes a great argument for using simple early-1940s characters as the basis for animation practice. By then, animators had nailed down the best practices for animating, but were still tentative about moving beyond typical pear-shaped characters. So they’re perfect vehicles for a beginning animator to conceptualize how cartoons move and carry their weight, without getting thrown off by any zany stylization that later evolved.
So, after trying to animate a girl with a ponytail, I think my next twick will be the mercifully bald Elmer Fudd.
