Birthday Celebration Portrait

Use the uploaded user photo as the ONLY identity reference for the human subject. Preserve the user's exact recognizable identity with maximum fidelity: facial structure, face shape, forehead, eyebrows, natural eye shape, nose, lips, mouth proportions, cheekbones, jawline, chin, skin tone, natural skin texture, hairline, facial hair if present, and all distinctive features. Do NOT copy the identity or facial characteristics of the woman in the reference image. The user's face must remain unmistakably the same person from the uploaded photo. Do not beautify, slim, reshape, age, de-age, feminize, masculinize, or otherwise redesign the user's identity.
Recreate the reference image as a highly realistic celebratory birthday portrait while replacing the reference person's identity with the user's uploaded identity. The final subject stands centered in a vertical full-body composition, facing the camera in a relaxed, elegant three-quarter/front-facing stance. Her upper body is upright and poised, shoulders relaxed, with her head slightly turned and gently tilted toward the camera. Reproduce the reference's warm, genuine, cheerful expression: a soft closed-to-slightly-open smile with relaxed cheeks, bright friendly eyes, naturally raised/relaxed eyebrows, and a happy celebratory mood. The eyes look directly toward the camera. The reference expression, gaze, head orientation, and emotional state must override the expression and gaze from the user's source photo while keeping the user's identity unchanged.
The subject holds a small round birthday cake in her left hand, extending the cake slightly outward at approximately waist-to-chest height. The cake rests on a simple round cake board and is a light cream/vanilla-colored layered cake with textured frosting, a few small cream decorations and subtle red/pink accents on top. A single tall thin candle rises from the cake, with a small warm flame glowing above it. Her other arm is bent naturally across the front of her body, holding a large lush bouquet of fresh flowers against her torso. The bouquet contains prominent red roses, creamy white roses, pale pink flowers, small white blossoms, abundant green leaves, and long green stems, wrapped in rustic natural brown/gold textured paper and tied with a large elegant beige satin ribbon. Preserve realistic hand anatomy, natural finger placement, believable grip, and accurate proportions.
Dress the subject in a sophisticated floor-length black evening gown matching the reference. The gown has a fitted upper bodice with a semi-sheer black mesh neckline/upper panel, a subtly glittering or textured black central bodice, and a very full layered ball-gown skirt made from translucent black tulle/organza-like fabric. The skirt expands dramatically from the waist to the floor, with several overlapping flowing layers, delicate sparkle visible throughout the fabric, and natural folds and volume. Keep the dress elegant, feminine only if compatible with the user's identity, and anatomically appropriate to the user; never alter the user's gender identity merely to match the reference.
Hair should follow the reference's overall styling concept while remaining naturally compatible with the user's own identity: dark hair arranged neatly with volume, gathered or flowing behind the shoulders, with a few soft face-framing strands around the cheeks. Preserve the user's own hairline, texture, density, length, and distinctive characteristics rather than copying the reference person's exact hairstyle. Add only subtle elegant accessories consistent with the reference, such as small refined earrings, if appropriate.
Set the scene indoors against a warm beige/tan studio or celebration backdrop. Behind the subject, place enormous glowing white numerals “21” centered high on the wall, clearly visible and proportionally similar to the reference, with the subject standing partially in front of the lower portion of the numerals. The “21” should appear as large illuminated birthday signage or projected light, softly diffused around the edges. Keep the background minimal, uncluttered, warm, and elegant with no unnecessary objects, decorations, people, or text other than the large “21”.
Use warm cinematic indoor lighting with a soft amber/golden tone. The main illumination comes from the front and slightly above the subject, producing flattering but realistic light across the face, dress, cake, and bouquet. Include a subtle warm glow from the candle and gentle illumination around the large “21”. Maintain realistic soft shadows behind and beneath the subject, natural skin highlights, controlled contrast, and believable interaction between the subject and background lighting. Avoid harsh artificial beauty lighting or excessive skin smoothing.
Camera perspective should closely match the reference: a vertical full-body portrait photographed from approximately eye level or slightly below chest level, with the camera positioned several meters away so the entire gown from head to floor is visible. Use a natural portrait lens perspective around 50–70mm full-frame equivalent, avoiding wide-angle distortion. Keep the subject centered with the head around the upper-middle portion of the frame and the enormous “21” filling the background. The lower hem of the gown reaches near the bottom edge of the image while remaining visible. Maintain realistic body proportions and natural perspective.
Create a polished professional photography aesthetic: ultra-realistic, photorealistic skin, detailed fabric texture, realistic flowers and foliage, physically accurate candle flame, natural hands and anatomy, subtle depth of field, clean focus on the subject, gently softened background, cinematic tonal range, fine photographic detail, warm color grading, realistic shadows, and premium birthday editorial photography. Preserve tiny natural skin details and avoid plastic-looking retouching.
The final image should look like an authentic professionally photographed 21st-birthday celebration portrait, not an illustration or AI-generated composite. No extra people, no distorted hands, no duplicate fingers, no malformed flowers, no warped cake, no facial alteration, no identity drift, no exaggerated makeup, no body reshaping, no unnecessary props, no watermark, no captions, and no additional text. Priority order: 1) exact identity from the uploaded user photo, 2) reference expression, emotion, gaze, and head pose, 3) reference body pose and composition, 4) reference clothing, cake, bouquet, “21” backdrop and environment, 5) reference lighting, camera perspective, color, and photographic style. Aspect ratio: approximately 2:3 vertical, matching the original reference composition.
