Create a bold modern fast-food advertising poster featuring a spicy Korean crispy chicken burger paired with a sparkling lemon soda combo meal. Use a premium commercial poster composition in portrait orientation with a 4:5 aspect ratio. The layout should feel energetic, youthful, modern, and similar to global fast-food campaign advertising. Background split: Left side: warm cream white Right side: vibrant spicy red mixed with lemon yellow gradient Place the crispy chicken burger slightly left of center and the sparkling soda can slightly right of center. Both products overlap the two background sections and become the hero composition. Burger details: golden crispy fried chicken, spicy sauce dripping, fresh lettuce, glossy brioche bun, cheese layer, realistic texture, cinematic food lighting. Drink details: premium metallic lemon soda can with condensation droplets, cold reflections, sparkling fizz effect. Behind the combo place giant lemon slices and spicy chili textures. Add floating chips, soda splashes, smoke accents, spice powder, crispy crumbs, and dynamic abstract wave shapes around the poster. Add modern abstract elements: fluid geometric shapes, curved transparent overlays, dynamic splash arcs, glowing particles, gradient motion streaks. Large vertical typography: “SPICY COMBO” Use oversized white typography partially cropped by poster edges. Top-left: minimal logo placeholder “ZESTA x CRUNCHA” Headline: “Crunch Meets Refreshment” Feature text: “Hot Korean Chicken • Ice Cold Lemon Soda” Style: premium fast-food campaign, cinematic food photography, energetic commercial design, glossy lighting, vibrant modern branding, realistic textures, dynamic composition. Negative prompt: cartoon food, blurry burger, distorted drink can, duplicated food, messy layout, unreadable text, watermark.
