Do you have a fixation when designing characters? Mine is that I prefer the cat eye shape, and literally any other shape, before the cute round one.
My OCs rarely tend to be cute, these days. And it's been long since I drew fanart of a character that had thar eye-shape.
-- in fact, my chibi of Lumine should've had round eyes, but I drew it when I was fairly new to the fandom, thus I messed up quite epically 😂
