Identity, Hair and Gender – 100% Match for REAL PERSON and 3D CHARACTER (CRITICAL)
“Use the attached photo as the only identity reference and preserve 100% of the person’s real appearance for both the realistic person and the 3D character.
The 3D stylized character must look exactly like the same person from the uploaded photo, with identical facial features, bone structure, skin tone, eye shape, eyebrow shape, nose, lips, jawline and chin. The 3D clone must keep the same hair style (length, volume, color, hairline) and the same gender presentation as in the reference image, without caricature distortion of the face.
Do not change the person’s gender, do not feminize a masculine face or masculinize a feminine face, and do not alter ethnic traits or age. No face swap, no beautification, no slimming, no makeup changes that modify identity. The viewer must instantly recognize that both the realistic person and the 3D character are the same person from the original photo, only rendered in different styles for this mixed real + 3D character scene.
If there are two people in the reference, each one must have their own 3D clone: keep each identity consistent and do not merge or swap faces. Every real face and every 3D face must still match exactly the original person from the uploaded image.”
Positive Prompt – Real Person with 3D Character Holding Their Shoulders
“Recreate the uploaded person(s) in a hybrid studio scene where a stylized 3D cartoon character is holding the real person from the photo by the shoulders.
Composition and interaction:
Keep a neutral studio framing and angle similar to the example: full‑body or three‑quarter body shot on a seamless background, centered composition.
The real person from the photo appears in front, in realistic style, facing the camera (or at a very similar angle to the original image).
A 3D stylized character (3D clone of the same person, with 100% facial, hair and gender match) stands just behind the real person and holds them firmly by the shoulders from behind, with both hands clearly resting on the real person’s shoulders or upper arms.
Ensure natural physical contact: the 3D character’s fingers curve correctly around the shoulders/upper arms, with proper anatomy, no clipping, no floating hands.
Identities and styles:
The real person is rendered realistically, preserving 100% of facial identity, hair style, gender and body type from the uploaded photo.
The 3D character is a stylized 3D clone of the same person, in a high‑end 3D cartoon / toy style with smooth materials, slightly exaggerated hair volume, and simplified body proportions, but the face remains instantly recognizable as the same person.
Both figures share a coherent pose and expression, conveying friendship, protection or playful support.
Clothing and look (Brazil flag jacket):
Give the real person and the 3D character coordinated outfits:
Jackets designed with Brazilian flag colors – rich green, bright yellow and deep blue, arranged in bold color blocks or stripes that clearly reference the Brazilian flag palette (approximately green #009B3A, yellow #FEDF00, blue #002776).
Keep blue jeans and white sneakers to complement the jacket, so the overall look stays clean, modern and sporty.
Fabrics should show soft folds and realistic shading on the real person, and polished stylized folds on the 3D character.
Lighting and background:
Use soft, even studio lighting, with gentle shadows on the floor to ground both figures.
Background is a clean, solid-color or subtle gradient in muted blue/gray tones, without props or distractions, like a professional character photoshoot.
Quality and rendering:
High resolution, sharp details on faces, hair, and clothing seams, with clean antialiased edges.
Professional compositing so that the real person and the 3D character share the same light direction, color temperature and contrast, making them look like they truly occupy the same space.
Premium 3D illustration / cinematic promo image quality, suitable for advertising or social media campaigns.”
