Film-quality Foundation series salt flats style

Vast and completely flat{argument name="terrain" default="Salt crust plain"} Extending to a clear horizon. Overcast, low-contrast sunlight filters through the thick {argument name="sky color" default="Dusty orange sky"} Filtering. The hazy, dim sun cast long, weak, and diffuse shadows. A solitary, tiny figure stood {argument name="structure" default="The Vault in the Foundation series"} Beside the pedestal. The dome is a massive, miles-high asymmetrical geometric polyhedron, exhibiting a dark, matte obsidian texture that reflects a dull, oily sheen. The scale contrast shrinks human figures to tiny specks relative to the structure's enormous vertical cross-section. Shot using a wide-angle anamorphic lens with deep depth of field, keeping both the cracked texture of the salt flats and the top of the polyhedron sharply in focus. The color palette is limited to industrial monochromatic: deep slate grey, matte carbon black, and soft sandy ochre dust. Wide-angle sci-fi movie still, used to create concept art. Lens flare, glowing neon lines, high-contrast cinematic flare, motion blur, vignetting, watermark, additional background figures, organic landscape.
