A realistic Japanese black-and-white manga style with steady, delicate lines, similar to the style of manga artist Naoki Urasawa, focusing on character expression and environmental realism. Employ a wide-angle long shot, placing the man as a relatively small silhouette in the lower third of the frame. The square is vast and empty, its ground made of wet stone slabs after a rain, reflecting the outlines of the surrounding buildings and the sky, enhancing the sense of depth and the cold atmosphere. In the distance are towering, stylistically mixed urban buildings, fading into mist or shadow. A few pigeons walk on the square or are startled into flight, serving as the only dynamic elements in the picture. The man wears a classic trench coat, its hem gently lifted by a breeze. His hands are in his pockets, his posture relaxed, but his back view appears solitary. Creating Light and Atmosphere: 1. The light source is the even, diffused light from an overcast or twilight sky. There is no strong direct light, so the shadows are soft and layered. The sky can be represented by a large area of negative space, or by using a very light gradient screentone to suggest clouds. 2. The reflection on the ground is key. The wet, slick surface acts like a mirror, connecting the man's reflection, the buildings, and the sky, creating an unreal, dream-like feeling. 3. The texture of the trench coat is expressed through fine wrinkles and the fabric's weave, making it look damp and heavy. 4. Although it's a long shot, the man's posture must be clear: his head is fully raised, focused on the sky, making the viewer wonder what he is looking at and what he is thinking.
