Ultra-realistic Beach Chest-Up Portrait with Identity & Hair Lock

Chest-up ultra-realistic beach portrait of the subject using the attached face reference [FACE_REFERENCE_IMAGE] as the exact identity source. Preserve the subject's exact facial identity and every natural facial characteristic from the reference, including face shape, jawline, eyes, eyebrows, nose, lips, ears, skin tone, facial hair, tattoos, pores and natural skin texture.

Use the hairstyle only from the reference image and preserve the exact hairline, density, volume, length, texture, natural shape, silhouette and strand direction; do not change, shorten, shave, fade or replace the hair. The subject is shirtless, wearing dark rectangular sunglasses, a thin silver necklace and small earrings. Frame from the chest upward; body angled slightly toward the camera while the head turns to the side for a calm profile-like composition. Expression locked: relaxed, calm and masculine; no smile.

Bright direct sunlight with realistic shadows across the face, neck and chest. Background of soft ocean water, clear sky and a simple natural beach atmosphere. Style: casual summer vacation photo with strong everyday realism and profile-photo appeal. Technical parameters: shallow depth of field, medium-format perspective, preserve natural skin texture and avoid beauty filters. Avoid different identity, altered face, fake tan, exaggerated muscles, feminine expression, plastic skin, smile, changed or different hairstyle, buzz cut, shaved sides, fade haircut, altered hair volume, wig, CGI or artificial beach background.
