something very minor that always grinds my pepper is when mermaid societies are depicted with buildings that are only a few stories like ours, especially when they have fucking roads. like??? i don't know if anybody has noticed, but mermaids can swim in any direction they like, including UP. why the hell would they resrict themselves to the bottom of the ocean?? you fools. you IMBECILES. they would build into canyonsides and stack those buildings up on top of each other as much as they please. think of the aesthetic possibilities!! patchworks of differently colored squares on a cayonside to denote where one shop starts and another ends!! building fronts being carved into to create decorations!! merpeople darting up, down, left, right, diagonal, all swooping around each other with ease bc the sidewalk can't be cramped if there's no sidewalk!! C'MON!!
