A quick experiment to see if Mike M’s “Jack Kirby in 3D” dream is actually possible. The style can certainly be approximated, and quickly.
Yes, I know, shadows and other embellishments would need to be added. The colours would also need to be muted back to more of a “faded 1960s comic-book” look (I’m not a fan of garish re-colours of 1960s comics, printed as reprints on slick white paper). A firmer holding-line would need to enclose the character, and some clean up is needed on the over-complicated head.
