A realistic black-and-white manga style, with fine lines and masterful use of rich grayscale and screentone effects to depict detail, creating a serene yet melancholic atmosphere. Employ a high-angle panoramic composition, as if the camera is hovering above the coast, looking down upon the boundary between the city and the sea. The composition is stable, emphasizing the horizontal line (the sea level) and vertical lines (the crumbling buildings). In the foreground are a broken seawall and streets inundated with seawater, with a few burnt-out cars half-submerged. The mid-ground features the main body of the city's ruins, where countless skyscrapers are reduced to skeletal frameworks, their dark, hollow windows like the eye sockets of skulls. From deep within the ruins, several thick columns of black smoke rise vertically into the sky before being dispersed by the wind high above, merging with the gray clouds. In the far distance is a calm but somber-toned sea, with the silhouette of a half-sunken battleship or cargo ship possibly floating on the horizon. The lighting and shadow design is key: set under the diffused light of an overcast sky, with no harsh, direct sunlight. This makes all shadows in the scene very soft but rich in layers. The shadows of buildings, smoke, and clouds intertwine, forming a delicate transition from deep gray to light gray. The sea reflects the gray of the sky, devoid of sparkling waves, possessing only a heavy, lead-like quality. The entire scene lacks drastic motion; there is only the silent lapping of waves against the ruins and the whisper of wind blowing through the hollowed buildings, filled with a post-apocalyptic tranquility and sorrow.
