Thanks!! The cat is Cookie Cat from Steven Universe. I have only a vague idea of what banding is/have a hard time understanding what a good alternative to it is but I'll try to do do more research to figure it out and then maybe fix what I've got. I think I'm probably just going to take out the yellow part on his outfit as well because I think it'd be better without any shading at all (idk why I added that honestly??)
