Monochrome editorial portrait with sculptural lighting

Create an ultra-realistic monochrome editorial portrait using the uploaded reference image strictly as the sole identity source. Preserve 100% exact facial identity, bone structure, jawline, cheekbones, nose, lips, eye shape/spacing/gaze, skin tone/texture, hairline, hairstyle, and density—no beautification, reshaping, stylization, aging, or identity drift. Young man with calm neutral expression and direct camera gaze, quiet confidence. Naturally styled hair with subtle sheen and realistic skin texture. Wearing an oversized black mock-neck/turtleneck in thick structured fabric. Medium close-up, centered, subject in lower two-thirds with generous headroom. Clean seamless studio background. Single hard key light creates sculptural contrast: sharp diagonal beam from upper-left to lower-right across background, illuminating one side of face while the other falls into deep cinematic shadow; soft-edged subject shadow on wall. Strict grayscale, deep blacks to bright highlights, smooth tonal transitions, no color tint. Ultra-sharp eyes, high clarity without oversharpening, minimal grain, professional editorial finish preserving realism. Minimal, moody, architectural film-noir/high-fashion aesthetic. 4:5 aspect ratio.
