Create a dystopian cityscape set in the post-apocalyptic future during a cloudy afternoon. The art style should be grunge art with a high-angle view. The scene should depict a decaying and desolate urban environment, with crumbling skyscrapers, abandoned buildings, and overgrown vegetation reclaiming the city. The atmosphere should be bleak and oppressive, with dark clouds hanging low and casting ominous shadows. Scattered remnants of civilization, such as rusted vehicles and broken infrastructure, should be visible. A few survivors in tattered clothing can be seen scavenging for supplies amidst the ruins, highlighting the harsh reality of this dystopian world. The color palette should be muted, with earthy tones and a gritty texture emphasizing the sense of decay and desolation.
