Duolingo-style characters

Draw original characters the way Duolingo's illustrators draw theirs. Every rule here comes from Duolingo's public brand guide ("Shape language", design.duolingo.com/illustration) or from measuring the vector drawings published in it (raw numbers in reference/measurements.md).

Make new characters in this style. Never copy Duolingo's own characters (Duo, Lily, Zari, Bea, Vikram and the rest) or its logo: they are trademarks.

The frame

Draw every character in one frame: the head is 100 units wide and its center is (0, 0), with y growing downward. All numbers below use that unit, so the proportions survive any size. To place the character in a scene, translate and scale the whole group.
