{ "prompt": "Create a premium editorial Halloween product poster featuring a vampire bubble tea, illustrated entirely in an authentic 1930s–1940s vintage advertising style. Portrait composition, 3:4 aspect ratio.\n\nSUBJECT: A tall transparent cup of creamy caramel milk tea, centered and fully visible, filled with angular ice cubes at the top, glossy black tapioca pearls concentrated at the bottom, irregular brown sugar syrup streaks along the interior and small condensation droplets. A thick purple straw extends upward, leaning slightly left. The drink remains appetizing, with no face or limbs.\n\nVAMPIRE COSTUME: A flowing black cape wraps around the cup, opening at the front to reveal the drink. Deep violet lining, broad sculptural folds and a dramatically raised angular purple collar frame the upper cup. The cape spreads across the tabletop on both sides. A delicate antique silver chain crosses the upper front of the cup, fastened with a small sculpted bat clasp.\n\nCOMPOSITION: The cup stands on a low cylindrical dark plum pedestal. Its silhouette dominates the center, while the collar fans outward behind it. A brown bat-shaped cookie with two small ivory eyes rests against the pedestal's upper-right edge. Keep clear visual separation between the beverage, cape and background.\n\nBACKGROUND: A mottled burnt-orange backdrop with dark charcoal distressing around the perimeter. A large soft-edged black bat shadow occupies the upper-left area. Fine hand-drawn cobwebs stretch inward from both sides. Two melting black candles in antique brass holders stand behind the product on the left. A large glowing jack-o'-lantern fills the lower-left background; a smaller round-eyed carved pumpkin sits on the right.\n\nFOREGROUND: A shallow black bowl of glossy tapioca pearls at bottom left, scattered translucent amber sugar crystals below it, a miniature carved pumpkin near bottom center-right and a small black spider at bottom right. A wooden tea scoop spilling loose black tea sits along the left edge. Sparse rusty autumn leaves decorate the lower corners.\n\nEXACT VISUAL LANGUAGE: Hand-drawn commercial illustration with confident black ink contours of varying thickness, rounded stylized forms, opaque gouache-like painted color fields, selective crosshatching, engraved-looking directional strokes and fine stippling. Build volume with graphic shadow shapes and restrained painted highlights. Render every object in the same illustrated medium, including the cup, ice, condensation, fabric, metal and food. Combine detailed product illustration with simplified vintage Halloween scenery.\n\nPRINT FINISH: Dense tactile paper grain, uneven ink coverage, subtle halftone wear, tiny scratches, faded pigment, dark speckling and lightly misregistered lithographic edges. Include a narrow irregular parchment-colored worn border, scuffed corners and faint fold marks. Distressing must feel embedded in an antique printed poster.\n\nCOLOR AND LIGHT: Dominant pumpkin orange, ink black, rich violet, warm caramel beige, antique brass and parchment ivory. Preserve strong purple cape accents and natural creamy beverage colors. Warm golden highlights on the ice, cup rim and pearls; deep graphic shadows inside the cape. Pumpkin interiors and candle flames use flat warm yellow shapes with restrained illustrated halos. Spooky, playful, nostalgic and polished, with strong editorial product hierarchy.\n\nNo typography, no headline, no logo, no watermark.", "negative_prompt": "photorealism, photography, modern 3D rendering, CGI, glossy digital airbrush, modern vector art, anime, pastel children's illustration, realistic image with a grain filter, neon lighting, excessive bloom, monochrome sepia, washed-out purple, added characters, skeletons, cats, face on the cup, limbs on the cup, illegible lettering, text, logos, watermark, collage", "aspect_ratio": "3:4" }
