i might try looking for some! i don't think i could use much from the comics (overlapping objects, and too small/visually messy to convert to thread design), and things he's coloured are right out because i've never done the 'large areas entirely filled in with colour gradients' needle-painting style (and i'm less interested in learning that than working with the different texture effects of a variety of one-colour-at-a-time stitches), and at that point monocolour outline embroidery of a character standing alone just isn't the most interesting embroidery. but something might be worth a try, chibis or floating blog heads...
