Generate Cyberpunk Hacker Portraits

Use the provided reference image as the person. Preserve the person's identity, facial features, age, hair, skin tone, body shape, and natural expression and gaze from the reference image. Do not copy any actor's likeness. Create a photorealistic cyberpunk character-inspired portrait: Aspect ratio: 4:5 vertical. Scene: a dim underground computer room with stacked CRT monitors, server racks, tangled cables, and faint green code reflections on glass. Subject: the reference person styled as a reality-bending hacker, wearing a long black coat, dark shirt, small oval sunglasses lowered enough that the face remains visible, and fingerless gloves. Action and gaze: standing beside a desk of old monitors, one hand resting near a keyboard; preserve the reference expression and gaze. Composition: waist-up, eye-level, subject centered with monitors forming a recognizable background. Lighting: cool monitor glow on one side of the face, soft overhead practical light to keep facial features clear. Details: leather coat texture, dusty CRT glass, cable clutter, keyboard wear, realistic skin texture, contact shadows. Text: no in-image text. Constraints: no watermark, no extra text, no logos, realistic anatomy, natural hands, no heavy retouching, avoid overly glossy sci-fi styling.
