Hans Christian Andersen's fairy tale of a dreamlike city-state, with a pink and blue gradient sky at dusk, the sky filled with scattered starlight, layers of beige stone buildings, warm orange lights shining through the windows of the houses, a huge ancient stone arch bridge, a mirror like calm river water, the water surface reflecting the city, clouds and trains in its entirety, a retro milky white rail train walking along the water surface track, the windows emitting warm light, only small black silhouettes of pedestrians on the bridge, hazy movie soft light, low saturation macaron color tone, quiet and distant, surreal fantasy, delicately writing a sense of substance
