  "prompt": "Use the reference photo strictly as the identity reference. Preserve the exact person, facial structure, hairstyle, age, gender, and overall likeness. Do not add or remove any person. Transform the subject into a notebook-style pen doodle illustration.\n\nIllustration Style:\nHand-drawn doodle created with [blue or black] ballpoint pen on lined notebook paper. Lines are thin, sketchy, uneven, and slightly shaky, as if casually drawn in a school notebook margin. Includes quick cross-hatching and imperfect outlines.\n\nColor & Texture:\nMonochrome pen drawing on lined notebook paper texture with subtle horizontal blue lines. Accent with very sparse, light pastel highlights in [very light yellow, pink, or mint]. Coloring is minimal, flat, and scribbly.\n\nFacial Features & Proportions:\nSimplified cartoon doodle face with dot or oval eyes, a small curved smile, and minimal nose line while retaining recognizable identity and hairstyle. Stylized doodle proportions with a slightly oversized head and simplified, gently rounded stick-like limbs.\n\nShading & Lighting:\nNo photorealistic lighting. Light pen hatching and casual scribbles for minimal flat shading.\n\nBackground & Mood:\nOff-white lined paper background decorated with subtle hand-drawn margin doodles such as small stars, arrows, hearts, and clouds. Cozy, nostalgic, playful, and casual doodle aesthetic.\n\nConstraints:\nNo photorealism, no 3D render, no glossy digital painting, no anime or vector art. Pure hand-drawn pen-on-paper look.",
