Did at home on a boring evening. I could not find my geometry tools so I used a ikea plastic glass to make circular shapes. It was such a fun way to find alternative solutions! Also I'm a 3D modeler, I never learned how to properly draw other than sketch stuff for reference. I tried to ink it with a fine stabile 4mm pen, It look ok, one day I may even shade it, but for now I scanned it without color. My daughter now can color her favorite character after print.
