My first reaction to this was "What the fuck, clown lore??????" And then I read it, and my reaction still stands: This is so out there and whimsical, and also a bit terrifying, and I love it. I don't know what it is about clowns on this site but people have taken the concept, cranked it up to 11, and made something that little else matches on the wacky scale. Which, like, makes sense — it's fucking clowns.
I have read very little of the attached canon here, though I will say that this works well as a standalone piece.
I wish more people would adapt their concepts for the Serpent's Hand Format. It's one of the most versatile formats out there, I think, and doesn't get the love it deserves because so few people read GOI formats. In a way, I'm happy this is a SH format and not an SCP. You would not have been able to adequately convey the LSD trip that is Clown Town in any other way. (As an aside: I think there is something about your writing that is always able to evoke a mystical atmosphere in things. And here, it shows.)
