I've been chopping up some public domain art, collaging it together into art, somewhat similar to Johan Nohr's design on Into the Odd: Remastered, though not as colorful. A little more home printable, a little less Raygun Magazine. And I'm really happy with the results so far, so this will almost certainly be the art style for my nearly-finished game.
This one tableau I just slotted into the layout just absolutely slaps. I'll try to remember to share some art when I'm a little closer to pressing publish on itch.
