Tiny Off-Road Vehicle in a Colossal White Cavern AI Image Prompt

9:16 vertical, hyperrealistic epic environmental photography, minimalist sci-fi/surreal landform style, 50–70mm medium focal length, f/8–f/11, deep depth of field, frontal distant framing, highly symmetrical composition. The main subject is an unimaginably colossal white cave/canyon arch chamber, like a super-giant arched cavity sculpted by wind erosion and stratification. The surrounding rock walls are milky white, off-white, and light sand colored, their surfaces covered with fine flowing striations, sedimentary lines, folds, and wind-eroded textures; the textures drape from the top and curve down to converge toward the ground, forming a strongly enveloping spatial structure. Embedded in the layers are extremely fine transparent gypsum crystals/mineral fibers, with very faint starlight-like reflections when swept by diffuse light. At the center is a huge dark oval/teardrop-shaped abyss opening, almost pure black inside, extending upward to high in the frame, with an extremely oppressive feel. Far at the bottom of the opening is a tiny warm orange light point/firelight, with a little dust haze, reinforcing the sense of scale. The ground is flat, open white salt-alkali land, with subtle striations, shallow undulations, and salt-flower crystal cracks. In the lower-middle, slightly center, is a tiny dark off-road vehicle, parked alone on the empty ground, with an extremely faint warm white roof light on, faintly echoing the distant warm orange firelight. Across the very bottom foreground is a deep black band-like ground shadow/shallow water reflection band, creating strong light-dark contrast with the pale ground. Overall light is soft and restrained, diffuse skylight enters the opening, highlights are delicate without overexposure, shadows are deep. Color is extremely minimal: off-white rock walls + deep black cavity + faint orange-white glow. Slight film grain, quiet, lonely, mysterious, hyper-scale oppressive feel. English reinforcement: photorealistic colossal cavern chamber, monumental white eroded canyon arch, giant dark oval abyss, layered sediment walls with flowing striations, tiny gypsum crystal sparkles in rock layers, symmetrical composition, tiny off-road vehicle with faint roof light, small warm light.
