Notebook Pen illustration prompt Use ~ Gemini Nano Banana Pro Prompt: { "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 notebook-style pen doodle illustration. Illustration Style: Hand-drawn doodle made with blue or black ballpoint pen on lined notebook paper. Lines should be thin, sketchy, uneven, and slightly shaky, as if casually drawn in a school notebook. Cross-hatching, quick strokes, and imperfect outlines are encouraged. Color & Texture: Mostly monochrome pen drawing with limited soft pastel accents (very light yellow, pink, or mint). Paper texture should resemble real notebook paper with visible horizontal lines. Coloring should be minimal, flat, and scribbly. Facial Features: Simplified doodle face with dot or oval eyes, small curved smile, minimal nose or nose line. Expression should be calm, cute, and friendly. Avoid realistic facial detailing. Proportions & Form: Cartoon doodle proportions with slightly oversized head and simplified body. Arms and legs are thin, stick-like or softly rounded. Hands can be minimal line shapes. Shading & Lighting: No realistic lighting. Use pen hatching or quick scribbles for minimal shading. Keep the drawing flat and illustrative. Mood & Atmosphere: Casual, cozy, nostalgic, and playful. Feels like a cute doodle drawn during class or in a diary margin. Background: Lined notebook paper background with light pen doodles such as stars, arrows, hearts, clouds, or handwritten-style marks. Keep background subtle and uncluttered. Rendering Rules: No photorealism, no photo texture, no cinematic lighting, no digital painting, no anime, no manga, no 3D render, no vector art. Everything must look like a hand-drawn pen doodle on paper. Final Output: A charming notebook-style pen doodle illustration with simple lines, minimal color, and a nostalgic hand-drawn feel, maintaining exact identity from the uploaded image.", "negative_prompt": "photorealism, realistic skin, photo texture, cinematic lighting, hyper-detail, anime, manga, 3D, vector art, oil painting, digital painting, glossy skin, clean perfect lines, realism, face change, identity change, extra people", "quality": "high", "clarity": "high", "style_strength": "strong notebook doodle", "reference_usage": "exact face and identity preservation required" }
