AI Poster Prompt for Yokohama Summer Comic Style

"Create a vibrant retro Japanese pop-art travel poster for {argument name="city theme" default="Yokohama"}, in a bold comic-book style with thick black outlines, saturated summer colors, halftone dot textures, crisp cel shading, and dynamic layered typography. Use a vertical 3:4 poster canvas. The sky is bright cyan with white clouds, seabirds, speed-line shapes, and two tall palm trees framing the scene. At the top, place huge stacked headline text: “YOKOHAMA” in hot pink block letters with white and black outline, “POP” in oversized yellow halftone letters, and a tilted banner reading “SUMMER CITY” in blue on white. Below it, add a starburst label with the exact text “ZOMBIE GIRL & CHAPPIE” in pink, blue, and green. The main foreground features exactly two characters: a cute chibi zombie girl with pale blue skin, black bob hair, visible stitch marks on her face and limbs, huge round black-and-white eyes, a cheerful open smile, a pink short-sleeve dress covered in white hearts, black trim, white socks, black Mary Jane shoes, and one hand making a peace sign; beside her stands a tall friendly futuristic robot named {argument name="robot name" default="Chappie"}, with a sleek silver and charcoal humanoid body, rounded shoulder armor, black mechanical joints, green glowing cable accents, an OpenAI-style green emblem on the chest, one hand on hip, and the other hand holding a green glass soda bottle with a red-and-white straw and label reading “SODA”; leave the robot face intentionally blank/obscured by a neutral gray rectangular censor-like patch. Behind them, place a glossy {argument name="car color" default="pink"} 1950s American convertible with chrome grille, bumper, headlights, whitewall tires, and a small front plate reading “YOKOHAMA SUMMER.” The background should show Yokohama waterfront landmarks: a blue bay with railing, a skyline of modern high-rise buildings, the Cosmo Clock-style ferris wheel on the left, red brick warehouse buildings on the right, and a harbor promenade. Add exactly one pair of pink sunglasses lying on the pavement in the bottom left foreground, plus flower planters near the car. Make the composition busy but readable, like a collectible summer city poster, with no extra characters and no additional large text beyond the specified wording."
