In the Graphic Novel group, I'd add Castle Waiting by Linda Medley.
And query on two more:
1) Blankets by CraigThompson? It's arguably just memoir, but it's memoir turned into story; unclear how literally accurate rather than emotionally accurate it's meant to be.
2) And Watchmen? It's its own thing now, but when it was written it challenged superhero genre assumptions to the point of busting them open, didn't it? And it's an odd combination of comic and "files".
