Use the uploaded photo as the EXCLUSIVE and PRIMARY reference for the person’s face and character identity. The generated portrait must be 100% identical to the uploaded photo: same facial features, bone structure, skin tone, eye color, gender, perceived age, hairstyle, hairline, and overall facial proportions, with no beautification or alteration. GEOMETRIC & IDENTITY LOCK — ABSOLUTE: Read ALL facial geometry EXCLUSIVELY from the uploaded reference photo. Preserve exact nose shape, eye shape and spacing, lip contour, jawline silhouette, chin shape, cheekbone prominence, brow arch and thickness, ear shape and placement, forehead height and width. Keep every mole, freckle, scar, pore and skin texture detail, translated faithfully into ink values without erasing or smoothing them away. Do not apply symmetry correction, face slimming, or beauty filters. THIS IS A REAL PERSON — no artistic liberties with their underlying facial structure. ​ GENDER, AGE & EXPRESSION LOCK: The gender of the subject is determined EXCLUSIVELY by the uploaded photo — do not change or reinterpret gender. Preserve the same perceived age; do not make the person look younger or older. Preserve the exact facial expression from the uploaded photo as much as possible, converted into line and shading while keeping all expression landmarks (brows, eyelids, mouth corners) identical.​ ​ CROP & FACE POSITION LOCK — MATCH EXAMPLE: Match the same portrait crop and head position as the example ink artwork: head and shoulders or bust‑level framing on textured white sketch paper, centered composition. Keep the face orientation, tilt, and scale in frame equivalent to the example so that the new portrait feels like the same layout, but with the uploaded person’s identity. MAIN STYLE — MONOCHROME INK 3D ILLUSTRATION: Hyper‑realistic monochrome ink 3D illustration — a 99.99% accurate portrait of the person from the reference photo, drawn with black ink on textured white sketch paper. Fine‑to‑bold linework, delicate facial details, layered ink shading, and clearly visible paper grain. The portrait must look like an ink drawing that almost pops off the page in subtle 3D relief, but still clearly remains an ink illustration (not a photo with a filter). INK & PAPER RENDERING: Use a full range of ink values: ultra‑fine lines for hair and eyelashes, medium lines for contours, and bold strokes for deep shadows. Layered cross‑hatching and directional strokes define cheeks, nose, jaw, and neck, with soft transitions created by dense linework instead of airbrush. Textured white sketch paper is clearly visible in lighter areas, with grain peeking through the ink marks, especially in the background and highlight zones.​ HAND & CALLIGRAPHY PEN: A graceful right hand with soft, slightly feminine fingers appears in the scene, positioned above or near the lower part of the artwork as if still working on the portrait. The hand holds a calligraphy pen between fingers in a natural drawing grip, with subtle anatomical detail in knuckles, nails, and tendons, but rendered in the same monochrome ink illustration style. Nearby on the paper or desk, an elegant ink bottle is placed — small glass or ceramic, with visible reflections and ink inside, consistent with the monochrome palette.​ MEDIUM CONSISTENCY RULE: Everything in the frame — portrait, hand, pen, ink bottle, No full‑color elements, no photographic skin texture, no glossy 3D CGI look. The illusion should feel like a high‑end studio photograph of a physical ink drawing, but all subject content is itself drawn in ink. LIGHTING & DEPTH: Soft, directional studio‑style lighting across the paper surface, creating gentle shadows from the hand, pen, and ink bottle, emphasizing the 3D feel of the drawing and tools. Shadows should fall consistently according to one light direction, enhancing the sense of depth without overpowering the linework. High‑resolution, ultra‑clean image (4K–8K) where every stroke and paper fiber is crisply visible. ​​ AI CORRECTION BLOCKERS — ALL DISABLED FOR IDENTITY: symmetry correction = DISABLED face slimming = DISABLED beautification filter = DISABLED skin smoothing = DISABLED age regression = DISABLED gender reinterpretation = DISABLED NEGATIVE PROMPT: wrong person, changed facial structure, different nose, different eyes, different lips, altered jawline, changed hairstyle, changed hairline, changed gender, younger or older appearance, low‑detail face, generic handsome man, colored ink, watercolor effect, oil painting, charcoal, pencil sketch instead of ink, flat vector art, comic or manga style, messy scribble lines, no paper texture, photographic skin texture, color background, digital glitch effects, 3D CGI plastic look, out‑of‑place realism on the hand only, mismatched style between face and hand, missing ink bottle, missing calligraphy pen, Use your uploaded photo as Image Reference / Character Lock with a high weight (around 0.95–0.99) so Nano Banana preserves face match at 99.99% while fully converting everything into the hyper‑realistic monochrome ink illustration on textured paper.
