I’m in the process of learning the animation program Live2D for a future project, and this is the result of me testing the waters.  Overall, I’m really pleased with what I’m able to do with Live2D.  It’s not the most intuitive interface, but once I was able to wrap my head around the basic workflow, it was pretty quick and easy to produce this short gif.

(She’s heavily inspired by the work of stop-motion master Kihachiro Kawamoto, by the way.)
