a yellow classroom with a blue floor? what a fantasy, in real life classrooms are all sterile white (or black of you’re extremely lucky) and have absolutely no hint of warmth or life.
I’m honestly just glad my brain has erased all detailed memories of my time in school, best thing that ever happened to me was dropping out.
what seems to help from what i’ve seen is to make it more cartoony and less, you know, suspiciously detailed…
it will of course not work 100%, but it at least sort of sets the tone of it not being sexual, like how mickey mouse generally manages to avoid being sexualized.
