asterios polyp - david mazzucchelli (and also batman year one!)
diary of a teenage girl - phoebe gloeckner
black hole - charles burns (any charles burns, really)
we3 - morrison and quitely
my favorite thing is monsters - emil ferris
all lisa hanawalt comics make me cry laughing
some classics that are classics for a reason : all-star superman, dark knight returns, new frontier, watchmen
idk how many longer storylines you’re willing to get into (if any) but invincible is the greatest superhero comic of all time from beginning to end, the ed brubaker captain america stuff is amazing, y the last man, scalped, the miles morales ultimate spider-man stuff, the alan moore miracleman.
that‘s a ton but those comics all changed my life and i love them deeply!
