Using the CHARACTER REFERENCE IMAGE only for identity, create a photorealistic, hyperrealistic full-body studio portrait in strict 3:4 vertical aspect ratio, 8K resolution, ultra high definition, highly detailed, sharp focus, professional photography, masterful composition. Preserve maximum facial fidelity to the referenced person (face shape, eye spacing, brows, nose, lips, jawline, ears, beard/facial hair, hairline, hairstyle, age, natural asymmetry), with lifelike skin texture and natural eyes; no face-swap artifacts. Do not copy reference clothing. Dress the subject in a luxury minimalist tailored black or charcoal single-breasted two-button suit, selecting ideal jacket length, shoulder width, lapel style (refined notch or peak), and trouser cut based on their physique; pair with either a black shirt, tonal dress shirt, or fine knit turtleneck that best suits them. High-end black leather dress shoes or sleek boots. Preserve the original studio environment exactly: thin tubular-metal chair slightly left of center; relaxed seated fashion pose with crossed legs and natural arms. Maintain the large circular hard spotlight behind the subject with the same position, size, intensity, and soft edge; outside the circle, charcoal-gray background. Strong directional studio light from camera-left/front-left casts a crisp, corresponding shadow of subject and chair to the right; medium-gray floor with realistic contact shadows. 65–85mm lens perspective, generous negative space, premium monochrome grading with bright spotlight whites, deep suit blacks, strong shadow separation. No text, watermark, extra fingers, or inconsistent shadows.
