Ultra-realistic Portrait of a Man with Bougainvillea

An 8K ultra-realistic professional vertical portrait (minimum 7680 x 4320 pixels equivalent detail, 9:16 aspect ratio) of a young man standing outdoors in front of a dense wall of vibrant pink bougainvillea flowers, captured in soft natural daylight with exceptional sharpness and shallow depth of field; the subject is positioned centrally against the richly textured floral backdrop, creating a bold contrast between his neutral-toned outfit and the saturated blossoms, with fallen petals scattered along the ground at his feet; he has thick, slightly tousled black hair with natural volume, a neatly trimmed short beard and mustache, medium-brown skin tone, and defined facial structure, with his head tilted slightly downward and to the side, eyes cast toward the ground in a calm, introspective expression; his facial features must remain 100% consistent with the reference image, including identical jawline shape, nose structure, lip contour, eyebrow density, and overall facial proportions; he is wearing a light blue and white vertically striped button-up shirt with sleeves rolled to the forearms layered over a black inner shirt, paired with light gray straight-fit trousers; one hand is raised casually to the back of his head while the other loosely holds a small cluster of pink flowers, adding a natural candid feel; the composition emphasizes realistic skin texture, detailed hair strands, crisp fabric folds, intricate floral petal definition, balanced highlights and shadows, true-to-life color grading, and creamy background separation for a highly polished, editorial-quality outdoor portrait.
