A cinematic, realistic square profile picture of a mature, elegant man standing in quiet contemplation beside a rain-streaked window at dusk. His face is partially in shadow, revealing only a subtle, confident side profile. The scene features a beautiful contrast of lighting: a warm, golden glow from within the room illuminates his shoulder, while a cool, deep blue twilight with soft, blurred city bokeh shines from the outside. On a dark wooden table nearby, a classic, half-open hardcover book lies catching the warm light, hinting at a new chapter. Elegant, mysterious, and peaceful atmosphere. Shallow depth of field, focus on the delicate rain droplets on the glass and the silhouette of the man. Photorealistic, cinematic lighting, 8k resolution, masterpiece, highly detailed.
