Use this full structured prompt in Nano Banana with your uploaded face photo as the main character reference.
Identity lock (use the uploaded photo)
Use the UPLOADED PHOTO as the ONLY and EXCLUSIVE face and character reference. Keep the person’s identity 100% identical to the uploaded photo: same facial features, bone structure, skin tone, gender, age impression, hairstyle shape, hairline and overall facial proportions. The GENERATED CHARACTER’S GENDER MUST MATCH the gender in the reference photo; do NOT change or guess the gender. Do not make the face younger or older, do not beautify or slim the face, do not alter nose, eyes, lips, jawline or cheek volume. You may adjust only the facial EXPRESSION to match the scene (focused, intense fighter) while keeping the face 100% recognizable as the same real person. Preserve any unique details such as moles, freckles, scars or specific skin texture.
Positive prompt (main scene and style)
Ultra‑realistic, cinematic close‑up portrait of the uploaded person reimagined as a battle‑hardened martial‑arts fighter, with a modern AAA fighting‑game look. The character is framed vertically from spiky hair down to the upper chest, wearing a worn white karate gi with visible fabric weave, frayed edges and sweat‑darkened collar. The head is slightly bowed forward in a calm but intense focus, chin lowered, eyes looking forward or slightly up from under the brow, expression serious and determined, not smiling. Hair is thick, spiky and tousled, with layered stylized clumps but rendered in hyper‑realistic strands, catching warm highlights on some tips while most of the hair stays dark. The exposed chest is muscular, sweaty and lightly scarred or bruised, with patches of dried blood or battle marks if desired, reflecting light with glossy specular highlights. Background is dark and softly blurred, with subtle colored bokeh or arena lights, giving the impression of a fighting ring or stage without distracting detail.
Lighting block
Cinematic mixed lighting: a warm key light from above and slightly to one side, casting golden highlights on the top of the hair and along the gi collar and upper chest, and a cooler blue fill from the opposite side to add depth in the shadows. Sweat on the skin produces bright specular reflections, especially on the chest and along the neck, while soft shadows around the eyes and under the jaw sculpt the face and add drama. Background remains darker, with soft, defocused light blobs suggesting arena lights.
Lens, camera, crop and zoom block
Use a strong portrait zoom equivalent to a 70–100mm lens, with the camera positioned slightly above chest level, pointing straight at the character. Frame and crop the image EXACTLY like the reference: tight vertical close‑up from the top of the hair to just below the upper chest, cropping a little off the hair tips and cutting the torso so only the upper pectorals and gi collar are visible. Keep the face and chest centered, with shoulders touching or nearly touching the left and right edges of the frame. Depth of field is shallow to moderate: the face, hairline and gi collar are in sharp focus, while lower chest and background fall into soft blur, matching the same crop and zoom feeling as the example image.
Detail and rendering block
8K‑grade hyper‑real rendering: individual hair strands and clumps with soft motion and flyaways; clear texture in the gi fabric (stitching, weave, frays); pores, subtle freckles or scars on the face and chest; beads and streaks of sweat with realistic refraction and reflection. The chest shows fine skin texture beneath sweat and any light bruising, with accurate shading following muscle structure. Color palette balances warm browns and golds in hair and skin with cooler blues and grays in the shadows and background, giving a rich, cinematic look. Overall aesthetic: polished key‑art portrait for a top‑tier fighting game, combining stylized hair volume with realistic materials and anatomy.
Negative prompt
No different person, no changed gender, no changed age, no new hairstyle unrelated to the uploaded photo, no altered facial proportions that break identity. No full‑body view, no wide shot, no medium shot; keep the tight vertical close‑up crop described above. No cartoon, anime flat shading, low‑poly 3D, rough sketch or painterly oil style; keep high‑detail CGI / photorealistic rendering. No cluttered or bright background; no cityscape, crowd or textured wall—only soft, dark, defocused arena lights. No text, logos, watermarks or UI elements. No heavy motion blur, grain, pixelation or compression artifacts.
