A concept that I absolutely love (I wrote a story of it once but it's one of my weaker ones I feel) is the idea of an artist or other creative having a sudden urge to detail out an image of a nonhuman creature, only for them to suddenly realize that what they've made is a self portrait. Especially if I work in some tf induced by the Realization.
funny goops and pun-named drinks are perfectly good tf triggers but something hits about the trigger being "seeing Yourself for the first time"
oh right heres the doodle in question btw
