Grand Sci-Fi Landscape with Monolithic Ring

Before translationGenerate a 2:3 vertical grand sci-fi landscape with photorealistic natural textures, fine film grain, and restrained vintage cinematic grading. In the foreground are soft, undulating ochre-red hills, with a solitary adult standing slightly left of the bottom center facing away from the camera, wearing a dark long coat and occupying only 2.5% of the frame, quietly gazing into the distance. On the vast plains of the mid-ground, numerous tiny off-white settlements are scattered, with a silvery-blue river flowing in a gentle S-shape through the towns and reddish-brown land. Beyond the horizon stands a planet-scaled, slightly tilted ancient fractured stone monolith ring: the body is extremely heavy, with a massive curved solid occupying the upper left of the frame, its top and left edge cut off by the frame; a curved remnant on the right extends into the sky, its irregular break misaligned with the main ring; the center encloses an arched sky void expanding toward the upper right, not two straight parallel walls. The surface features deep bluish-black basalt-like rough layering, macroscopic fractures, and slowly weathering longitudinal gullies, definitely not a smooth metal ring. Warm golden low-angle sunlight skims from the right side across the curved inner edge and break, while the large main body sinks into layered dark green shadows, the bottom obscured by massive but calm milky-golden cumulus clouds and dust, like clouds accumulating at the feet of the giant object, not exploding. The sky on the right is deep greyish-blue, the hay is copper-red and dark ochre, and the river has only restrained natural reflections. Use the tiny silhouette, miniature towns, base clouds, and the ring extending beyond the frame to emphasize human insignificance. Quiet, distant, heavy, and incomprehensible grandeur, clear depth of layers, true natural light, no text, no logos, no watermarks, no lasers or flares.
