A specialized prompt for Nano Banana that preserves a person's identity from a reference image while adding a playful hand-drawn doodle shadow companion.
Prompt
Use the uploaded reference image as the strict identity and outfit reference for a realistic {argument name="subject" default="Japanese woman"}, preserving her face identity, facial proportions, eye shape, nose, lips, skin tone, hairstyle, hair colour, visible accessories, overall vibe, and outfit exactly as shown in the reference. Do not invent or hardcode features that are not present in the uploaded image. Create a high-quality vertical mixed-media portrait featuring a realistic full-body Japanese woman standing beside a black {argument name="shadow style" default="hand-drawn doodle-shadow"} version of herself sketched directly onto a {argument name="background" default="clean wall"}. The real woman should remain photorealistic, wearing the same outfit and styling as the reference, with a cute, slightly confused, mildly embarrassed expression as if wondering why she is playing along with her mischievous shadow. The doodle-shadow should be a lively black sketch version of the same Japanese woman, matching her hairstyle, outfit silhouette, and overall identity while having exaggerated cartoon expressions and energetic movements, surrounded by manga-style motion lines, hearts, sparkles, stars, and comic symbols. For every generation, invent a completely new playful pose where both the real woman and the doodle share the same general idea without perfectly mirroring each other. Avoid repeated pointing poses, finger-guns, or stiff standing poses, and instead create fresh playful actions such as dancing, balancing, sneaking, making a giant heart, peekaboo, dramatic overreaction, or other cute troublemaker poses. Place the real woman on one side of the frame and the doodle-shadow on the wall beside her so their interaction is immediately clear. Use a clean white, cream, or light grey indoor wall with minimal clutter, soft natural daylight, gentle shadows, and a polished editorial photography style. The final image should be ultra-detailed, social-media-friendly, with strong resemblance to the uploaded Japanese woman, faithful outfit reproduction, realistic photography combined with expressive black sketch line art, premium composition, and no AI artifacts. Avoid unrelated outfit changes, realistic second people, ordinary shadows, horror elements, coloured illustrations, anime humans instead of doodles, weak resemblance, cluttered backgrounds, repeated poses, text, logos, watermarks, distorted anatomy, extra limbs, extra fingers, or poorly drawn hands.
