Architectural oil painting wallpaper city futuristic melancholic

Create a widescreen cinematic sci-fi wallpaper in a cold, lonely oil painting style: the image shows a vast, foggy futuristic harbor city, the sky is pale gray-blue, towering vertical megastructures and needle-like skyscraper silhouettes loom faintly in the hazy mist. In the lower-left foreground, place a tiny, lonely human figure standing at the edge of a dark concrete pier with a simple metal railing, gazing at the magnificent city across the water reflected on the surface, emphasizing solitude and scale. The image must include 12 clearly visible flying vehicles: 2 large horizontal capital ships, one of which is a long, enormous spacecraft spanning the upper-left center, with faint warm orange engine light, and the other is a rounded, bulky spacecraft hovering on the right; 6 medium-sized airships scattered in the mist at upper left, upper center, center, middle right, far right, and lower left; plus 4 extremely tiny distant flying vehicles as tiny silhouettes in the background sky. The city is extremely rich in detail but softened by mist, containing platforms, docks, antennas, spires, faint lights, and reflections on the calm water. Use a soft color palette composed of ice blue, gray, light cyan, low-saturation beige, and subtle warm orange-red accent lights. Render with thick textured brushstrokes, presenting an impressionist oil painting texture, worn canvas texture, soft edges, diffused overcast light, and maximalist sci-fi detail in the distance, creating a melancholic atmosphere similar to a quiet coastal drama film. The composition fits a 2:1 horizontal desktop wallpaper, no text, no logo, no border.
