Reference: use the image I uploaded. Copy its crossed-arms pose and keep the facial structure exactly the same, so the person stays recognisably identical.
Subject: a young man, torso turned a little to the side, head tipped slightly down toward the camera, with a calm and confident expression.
Look: round dark sunglasses, very short cropped hair, a light trimmed beard and moustache.
Outfit: a black high-neck shirt with a dark textured overcoat layered on top.
Light: moody low-key studio setup; a soft directional key light from high on one side throws dramatic shadows across the face and the texture of the coat.
Background: a deep, dark gradient with a painterly feel.
Style: ultra-realistic cinematic studio portrait, DSLR quality, hyper-realistic skin texture, ultra-sharp focus, shallow depth of field, cinematic color grading.
Output: 8K resolution, vertical 4:5 composition.
