A collection of retro sci-fi character concept sheets rendered in a bold impasto gouache illustration style evoking 1950s–60s pulp science fiction and atomic age design. Characters span a diverse roster of human and fantastical races — lizardfolk, orcfolk, catfolk, elves, gnomes, tieflings, and more — each depicted in front, side, and back views in the tradition of classic animation and game concept art. Costumes blend retrofuturist space suits, long military coats, tactical harnesses, and analog technology into a cohesive atompunk aesthetic. The palette leans into saturated primaries — deep blues, burnt oranges, reds, and teals — with heavy visible brushwork, chunky paint texture, and strong directional light that gives every piece the feel of a painted illustration from a mid-century science fiction paperback.
