cinematic dark ai prompt | moody thriller lighting scene

A cinematic, dark-toned portrait of a young man sitting confidently in a brown leather armchair, wearing a dark formal suit with an open white shirt. He is positioned centrally under a single warm hanging lamp that casts a focused spotlight on his face and upper body. His expression is calm, intense, and introspective, eyes slightly closed, hands resting together near his lap. The scene is framed through a blurred keyhole-shaped foreground, creating a sense of mystery and secrecy. Low-key lighting, deep shadows, dramatic contrast, shallow depth of field, soft cinematic glow, film grain texture, symmetrical composition, psychological thriller mood, ultra-realistic, 4K, high detail, professional studio lighting, dark background, cinematic color grading, moody atmosphere.
