Retrato fotorrealista de un joven apoyado en un árbol

A highly detailed, photorealistic portrait of a handsome young man in his mid-20s, Caucasian, with tousled medium-length blond hair styled upwards, piercing blue eyes, light stubble and a short beard, perfect symmetrical facial features, subtle confident smile, direct eye contact with the viewer. He is casually leaning against the rough bark of a large tree on the left side of the frame, left shoulder resting on the trunk, both hands in the pockets of his beige/khaki trousers. He wears a fitted olive-green ribbed knit sweater with darker charcoal-gray ribbed collar, cuffs, and hem, the fabric showing realistic texture and slight folds. Background is a soft-focus misty landscape of rolling green hills under an overcast, diffused natural daylight sky, creating a calm and cinematic atmosphere. Professional photography style, sharp focus on the subject, shallow depth of field, natural soft lighting, high resolution, 8k detail, realistic skin texture and fabric details.
