Retrato de Primer Plano con Auricular en Clave Baja

Cinematic close-up portrait of a [serious adult man] in near-total darkness, tightly cropped on the right side of his face and left ear. He has short dark hair, thick brow, intense narrowed eye contact looking downward and forward, rugged skin texture, visible pores, light stubble, and a trimmed mustache. A single glossy white wireless earbud is inserted in his left ear, and one raised hand with long fingers is touching or adjusting it; exactly 1 earbud and 1 visible hand. Dramatic low-key lighting with a narrow hard key light from the front-left revealing skin texture, cheekbone, nose bridge, lips, ear, and fingers, while the background drops to pure black. Horizontal 16:9 frame, face occupying the right two-thirds, ear and hand on the left third, deep shadows, high contrast, muted natural skin tones, shallow depth of field, and subtle specular highlights on the earbud and skin.
