Continuous Single-Line Doodle Identity Preservation Prompt

Continuous Single-Line Doodle Identity Preservation Prompt

A detailed prompt for transforming a reference image into a minimalist, hand-drawn single-line continuous doodle illustration. It strictly requires preserving the identity of the subject while applying a stylized, artistic aesthetic with minimal color, flat shading, and a cozy, modern mood.

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 (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 art, oil painting, digital painting, glossy skin, sharp clean lines, realism, face change, identity change, extra people", "quality": "high", "clarity": "high", "style_strength": "strong minimalist doodle", "reference_usage": "exact face and identity preservation required" }

Triggering conditions: This skill must be used when a user provides data and requests "draw a chart," "generate a chart," "visualize," "make a graph," or "show me this data," or uploads CSV/Excel/spreadsheet data and wants to see a graphical representation.
