A breathtaking surreal editorial image: one enormous luminous red-and-white koi fish slowly swimming through the air above a futuristic coastal city at blue hour. The fish is gracefully curved, its translucent fins flowing like silk; windows and elevated walkways glow amber below, deep indigo skyscrapers fade into mist, a small crescent moon overhead. Dreamlike but convincingly photographed, sophisticated teal, coral and indigo palette, shimmering water particles suspended in the sky, cinematic scale and balanced composition. No text, no logos. Horizontal 4:3 composition.
