A city at night, the silhouette of a businessman standing in front of a large window, dressed in a suit with his hands in his pockets, a tired posture with his shoulders slightly slumped, the view is from directly behind, skyscrapers can be seen outside the window, pink, blue and green neon lights, the silhouette is pitch black, the city lights are reflected intricately in the raindrops on the window glass in the background, cool blue-purple and magenta tones, the raindrops running down the window, the texture and reflections of the glass, the geometric patterns created by the city lights, the area around the figure is slightly dark, emphasizing the sense of isolation, a film noir atmosphere, the sense of alienation in a modern city, a minimalist composition but a background rich in information, a fusion of photographic realism and artistic expression.
