I thought a fun way to get better at Ch An would be to make known superheroes and try to mimic their powers with the tools of the program, so I chose my childhood favorites the X-Men and a few of their villains. After I started making a bunch of them, I ended up tossing them together to make a faux version of the 90s theme song.
I think learning how to do something is way easier when you have a reference point of what a character should do and what you can use that character for. The main thing I learned though is figure out what you need that character for- if it's just 1 second of screen time, they don't need a full set of mouths and blinks and articulation and such. The first characters I made for this project do more and look worse and the later ones I made do less but look better, at least in my opinion.
