I had an idea for a cartoon. A witch who graduated witch school at the top of her class, only to find out that the industry has advanced farther than she could keep up, and she can't afford all the fancy ingredients and tools to perform professional witchcraft at modern standards. She has an animated cat familiar who has weird powers and helps her with her schemes to make a living. And a demon she summoned for her final exam who she can't get rid of because she signed a contract in blood, so now he just mooches off of her and lives rent-free in her apartment 'cause he's bound to her soul.
These designs are just drafts and I'm gonna try and refine them a bit more.
