Retrato de Estudio en Sepia de Hombre Musculoso Anónimo

Dramatic sepia-toned studio portrait of [a handsome muscular young man] seen from the upper torso up, centered and facing forward. He has tousled wavy dark-brown hair with golden rim highlights, broad shoulders, a defined chest and collarbones, a lightly hairy chest, and wears a dark worn athletic tank top with deep armholes and a scooped neckline. The face is completely obscured by a centered, opaque square block in warm medium brown, spanning from the forehead to the chin while leaving hair, ears, neck, shoulders, and torso clearly visible. Low-key cinematic lighting featuring a strong warm key light from the upper left, subtle rim light accenting hair and shoulders, deep shadows, and high contrast. Realistic skin texture, moody vintage sepia color grading. Dark mottled brown studio backdrop with soft vignetting, tight 1:1 square crop at upper arms and chest, photorealistic editorial fitness aesthetic, shallow depth of field, sharp detail on hair and torso, no text, no watermark.
