ultra-realistic 3d cinematic rendering, a 4:5 vertical chinese immortal celestial palace scene, unreal engine 5 level high-precision environment modeling, physically based material system, realistic global illumination, path-traced quality, cinematic volumetric lighting, high dynamic range. shot with a 16mm ultra-wide-angle lens from an extremely low ground angle, looking up at a city-sized white jade heavenly gate. the gate tower rises high and extends beyond the top of the frame, with two massive gate pillars dominating the left and right foreground, while the colossal central arch frames distant cloud-sea palaces and pavilions. the architecture uses ivory white jade stone, translucent light green jade, pale cyan-glazed roof tiles, and sparing restrained golden details. the pillars feature authentic relief carvings, cloud motifs, stone joints, subtle weathering, micro-wear, recessed shadow crevices, and delicate reflections. a broad white jade heavenly staircase ascends from the lower right into the archway, diminishing steadily toward a strong central vanishing point. at the center of the staircase stands only one extremely small white-robed immortal seen from behind, occupying less than 2% of the frame height, used solely as a scale reference. the sky is bright azure; the high sun on the right casts soft warm rim lighting, while the white jade surfaces carry subtle sky-blue environmental reflections. translucent mist and silk-like clouds curl around the pillars; distant palaces soften through atmospheric perspective while remaining legible in deep focus. overall palette of cyan-white, ivory white, pale gold, moderately bright exposure, realistic camera exposure, cinematic concept design composition, 8k-level architectural detail density. the final image must present believable space, massive weight, physically accurate lighting, and real-world materials as a finished ultra-realistic 3d cinematic render. negative prompt: 2d illustration, anime, manga, painterly concept art, hand-drawn brushwork, paper texture, chinese flat-color illustration, watercolor, ink wash, meticulous chinese painting, thick cartoon rendering, low poly, game screenshot, plastic model, miniature landscape, flat materials, fake lighting, gloomy sky, black clouds, underworld atmosphere, horror mood, ruins, dilapidation, traditional red palace gates, european castles, modern architecture, cyberpunk, neon lights, oversaturated gold, blown-out pure white, fisheye distortion, bokeh background, blurred background, crowded crowds, character close-up, deformed limbs, garbled artifacts, text, logo, watermark
