I have to say my inspirations are similar. I would add some random things I used to read for fun that I can't recall the titles too atm. Adams' books really helped me get a narrative voicing I feel, and old epics like gilgamesh I use for a sense of character arcs and overall archetype.
I sometimes borrow from life, although I suppose when I'm drawing I really go blank in my mind. I no longer see lines on a page when I try visualizing the characters or scenes, I see places I have once been to, or want to be at, and people in full detail, people I've not met as far as I'm aware.
