Create a creative ad in a 3:4 vertical format with a clean white background, bright studio lighting, and sharp details. Place a realistic photo of [a generic product] in the scene and blend it smoothly with black ink doodle artwork. The product acts like a magical gateway, with tiny cartoon adventurers stepping out into a fun illustrated world filled with floating islands, clouds, stars, and fantasy creatures. Use simple black line drawings with very little shading. Do not include any text, logos, brand names, trademarks, or copyrighted elements. The final image should combine a realistic product photo with imaginative hand-drawn sketches in a seamless way.
