Studio-Grade Dark, Moody, Photorealistic Portrait of a Young Man

Composition idea: generate a dark, atmospheric, photorealistic portrait of a young man (early 20s, slim face, pale skin, soft sharp jawline, messy medium-length wavy dark hair partially covering forehead). Background is a rough, textured wall with subtle stains and uneven paint, desaturated green-gray tones. Extremely grainy. Normal wavy hair. He wears a black high-neck turtleneck under a long black overcoat alongside soft matte fabric. Lighting is extremely low-key, coming from a soft side source (left side), creating deep shadows that partially obscure facial features while still keeping them faintly visible. Add heavy film grain, analog noise, restrained blur, and muted color grading. Com
