 "prompt": "Use the uploaded image strictly as the identity reference. Preserve the same person, exact facial structure, hairstyle, age, gender, body proportions, and overall likeness. Do not add or remove any person. Do not change identity. Transform the subject into a watercolor blob doodle illustration.\n\nIllustration Style:\nHand-drawn doodle combined with soft watercolor blobs. Line art should be minimal, loose, and slightly uneven, drawn with pencil or thin pen. Large parts of the character are formed using abstract watercolor shapes rather than strict outlines.\n\nColor & Texture:\nUse soft pastel watercolor colors such as peach, sky blue, lavender, mint, and warm yellow. Colors should bleed slightly, overlap naturally, and form organic blob shapes. Visible watercolor texture, paper grain, and soft edges are required. No sharp edges or clean fills.\n\nFacial Features:\nVery simple doodle facial features drawn on top of watercolor blobs. Dot eyes, tiny curved smile, minimal or no nose. Expression should feel calm, sweet, and friendly.\n\nProportions & Form:\nSemi-cartoon doodle proportions with simplified body shapes. Anatomy is loose and impressionistic, suggested more by color blobs than strict linework. Keep forms soft and rounded.\n\nShading & Lighting:\nNo realistic lighting or shadows. Depth is suggested only through overlapping watercolor blobs and slight color variation. Keep everything airy and flat.\n\nMood & Atmosphere:\nDreamy, gentle, cozy, and artistic. Feels like a modern children’s picture book or a handmade art journal illustration. Calm and emotionally warm.\n\nBackground:\nOff-white watercolor paper background with light pastel splashes, stains, or soft blob marks. Background should feel handmade and organic, not digital.\n\nRendering Rules:\nNo photorealism, no photo texture, no cinematic lighting, no digital painting look, no anime, no manga, no 3D render, no vector art. Must look like traditional watercolor and pencil doodle art.\n\nFinal Output:\nA soft watercolor blob doodle illustration with minimal line art and gentle pastel washes, preserving the exact identity from the uploaded image in a dreamy, hand-painted doodle style.",
