Design a moody, dark, highly detailed film poster for a sci-fi series concept set in a shabby futuristic city at sunset. In the foreground, depict a person wearing a dirty, worn-out shirt, picking up trash among scattered debris, damaged commercial ships, and crumbling buildings, emphasizing a gritty, dystopian atmosphere. The distant background features a majestic, futuristic city floating above the clouds, with a striking contrast between the two worlds – the shabby city below and the advanced metropolis in the sky. Small flying objects hover around the sky city, adding depth and a sense of technological advancement. The entire scene is bathed in a cinematic, vintage cyberpunk color palette, with dark tones accented by warm sunset hues and lens flare. Style the scene in a hyper-realistic, 3D manner, capturing intense detail and atmosphere.
