Risograph illustration poster, 9:16, strict three inks on cream paper #F4EBDD: warm orange #FF6C2F, olive green #5E6B3A, near-black #1E1E1E. Brown only where orange overprints olive. Skin is pale orange halftone over cream. White hair and beard are bare paper, never white ink. Black confined to glasses, shoes, tiny eyes and the tiny label.
Print must clearly show: slight registration offset leaving thin paper edges, fine ink grain with patchy coverage, coarse halftone dot shading instead of smooth gradients, semi-transparent overprint. Matte ink on fibrous paper. No 3D, no glow, no airbrush.
One cheerful elderly man: rounded blocky body, slightly short and round, gentle stoop, soft thick limbs, small bald head with a round paper-white beard, small round black glasses, olive cardigan and orange trousers, black slippers. Relaxed, pleased expression.
SCENE: The elderly man is pushing a wheelbarrow carrying one enormous pumpkin. The pumpkin is bigger than he is. Only the pumpkin is absurdly oversized and may be cropped by the edge; everything else, including the man and the wheelbarrow, stays normal size.
Subject fills 60–80% of the frame, calm cream negative space. Text: "GREEN THUMB" once, tiny bold black sans-serif in a free upper corner. No pink, no blue, no extra props, no other people.
