look into krita because i've used it before and it's kind of similar to how drawing works in blender 2d but it's easier to add colour (as opposed to blender 2d which I literally would have to wish on a monkey paw for it to properly work in a way that's easy and makes sense) (and that's a bad idea because then it's going to come back to bite me because that's how monkey paws work so it's not an option) (and also they arent real) but i've tried animating in krita before and it didn't seem to be as fluent as blener's animation so I GUESS WE'LL SEE WHAT HAPEns!P
