There are a lot of unknowns regarding Night in the Woods when it comes to the trophies/achievements and collectibles. The sketches you can find throughout the game only unlock when viewing certain events. Some of these happen automatically during the story, but the majority have to be worked for.
Weird Autumn Sketches have not been added as of yet. They do not affect the ability to get the ‘Seriously?’ trophy.
