Deadass, the idea literally was "Wouldn't be funny if he just... scribbles up there" since a lot of fictional iterations I see has him with a book on a podium. :v
But then I decided to explore the idea a little more instead of making a one-off joke like WHY St. Peter was chosen to begin with.
If I were to somehow have the chance to restart the series, I'd TOTALLY give him a renaissance art-style since the whole point everyone's a stick figure is that they 'funnel out what makes them different superficially (i.e. their appearance) and transform into what we perceive as things with no real individuality. Characters will have their "renaissance" when they return to their world.
