Elegant Birthday Photo Collage

Use the uploaded photo as the primary identity reference for the person. Preserve the person's exact facial identity, facial structure, skin tone, facial proportions, eyes, nose, lips, jawline, hairline, hairstyle and all recognizable facial characteristics. The final subject must clearly resemble the uploaded person. Do not copy the facial identity of the person shown in the reference image.
Create an ultra-photorealistic luxury birthday portrait collage inspired by the reference. Place the main uploaded person prominently in the center, shown from the waist up, wearing a light pastel-blue linen shirt with the top buttons naturally open and sleeves rolled up. Give him a relaxed, confident expression and natural fashion-editorial posture, with one hand lightly touching the shirt near the chest and a premium black smartwatch on the wrist.
Create three additional smaller portraits of the exact same person, maintaining the same facial identity, facial proportions, hairstyle, skin tone and recognizable features in every frame without variation. Each portrait should be inside a clean tilted diamond-shaped frame with a thin elegant gold border. The secondary portraits should show different natural expressions and poses, including looking sideways, smiling and wearing refined black sunglasses. Every face must unmistakably belong to the same uploaded person, especially the third frame. Do not introduce a different face, altered facial structure or different person in any secondary frame.
The second frame must contain only a logically composed portrait of the person. Do not add a separate, floating, cropped or disconnected hand. Every hand and arm must be naturally connected to the person's body and anatomically consistent with the pose. If the frame is a close-up portrait, crop the composition naturally so that no unnecessary hand appears.
Use a clean bright white studio background with subtle soft beige/gold brush-stroke textures and minimal golden decorative particles. Arrange the portraits in a balanced premium magazine-style composition with the central figure clearly dominant.
Add elegant typography at the bottom reading “HAPPY BIRTHDAY”, with “HAPPY” smaller above and “BIRTHDAY” large beneath it. Use sophisticated serif typography in dark navy and warm metallic gold, with a small delicate ornamental divider underneath.
Use soft high-key studio lighting, gentle shadows, clean highlights and a refined neutral color grade with bright whites, soft beige tones, subtle gold accents, pastel blue clothing and natural warm skin tones. Keep the overall aesthetic elegant, celebratory, minimal and premium.
