I'll only vectorize (either) Lightdragon, Yllumicoon, Gelum, Copycat, and/or Amethystcat once Leafcat draws them, but for now, I decided to fix Stuffbunny's design so that he uses my redesigned vector instead of my old vector of him, and also to be more consistent. I also changed Rubberrabbit's size to look more accurate, as well as adding back the line between the legs the bottom of his belly (albeit tweaked).
