Ultra-Realistic Black and White Portrait with Identity Lock

A prompt for generating an ultra-realistic, 8K cinematic black-and-white portrait of an 18-year-old man with a slim physique. The prompt strictly requires 100% face accuracy from an uploaded photo, but demands a completely new, attitude-heavy standing pose, angled three-quarters away from the camera. The subject has a cold, detached expression, with his gaze partially hidden by dark sunglasses, conveying a mysterious authority vibe.
