Continuous Single-Line Doodle Identity Preservation Prompt

Prompt

{   "prompt": "Use the uploaded image strictly as the identity reference. Preserve the same person, facial structure, hairstyle, age, gender, body proportions, and likeness exactly. Do not add or remove any person. Do not change identity. Transform the subject into a single-line continuous doodle illustration.\n\nIllustration Style:\nCreate a minimalist, hand-drawn single-line doodle where the entire subject is drawn using one continuous, unbroken line. The line should feel fluid, organic, and slightly imperfect, like a pen never lifted from the paper. Style should look artistic, playful, and intentionally simple.\n\nLine Quality:\nUse smooth but slightly shaky pen or pencil lines. Thickness can subtly vary to add character. Avoid clean vector precision; lines must feel human and hand-drawn.\n\nColor & Texture:\nPrimarily monochrome line art ({argument name="line color" default="black, dark brown, or soft navy"}). Optional very light pastel watercolor blobs or crayon patches behind the subject for warmth. Coloring must remain minimal and flat.\n\nFacial Features:\nExtremely simplified facial features formed naturally from the continuous line. Dot or small oval eyes, tiny curved smile, minimal facial detail. Expression should feel calm, friendly, and charming.\n\nProportions & Form:\nStylized doodle proportions with simplified shapes. The form should be recognizable but abstracted, maintaining likeness without realism.\n\nShading & Lighting:\nNo realistic shading or lighting. Depth is suggested only through line flow and spacing. Keep everything flat and illustrative.\n\nMood & Atmosphere:\nCreative, modern, calm, and cozy. Feels like an artsy sketch from a minimalist children’s book or creative journal.\n\nBackground:\nPlain off-white or soft pastel paper background. Optional light doodle marks or watercolor stains, kept very subtle.\n\nRendering Rules:\nNo photorealism, no photo texture, no cinematic lighting, no digital painting, no anime, no manga, no 3D render, no vector art. Must look like a genuine continuous hand-drawn doodle.\n\nFinal Output:\nA minimalist single-line continuous doodle illustration with soft artistic charm, preserving the exact identity from the uploaded image in a playful, modern doodle style.",   "negative_prompt": "photorealism, realistic textures, photo texture, cinematic lighting, hyper-detail, anime, manga, 3D render, vector...
