물에 잠긴 서울 도심

An impressionistic and dramatic painting of a city street in Seoul submerged in floodwater after a historic downpour. Cars are partially underwater, their headlights reflecting dimly on the murky surface. The surrounding modern buildings are dark against a stormy, gray sky, conveying a sense of urban paralysis and the overwhelming power of nature. The scene is somber and devoid of people. The style should be vibrant watercolor or gouache, artistic and expressive, with a bright, hopeful atmosphere. Use rich textures, sunny tones, and colorful elements to capture community energy, while keeping the composition balanced for a professional book cover illustration.
