Vast salt plain with giant dark vault and lone figure AI Image Prompt

Vast, completely flat {argument name="terrain" default="salt crust plain"} stretching to a sharp horizon. Overcast, low-contrast daylight filtered through a thick, {argument name="sky color" default="dusty orange sky"}. Hazy, dim sun casting long, faint, diffuse shadows. A single, tiny human figure standing isolated at the base of the {argument name="structure" default="Vault from the Foundation series"}. The Vault is a gargantuan, miles-high asymmetric geometric polyhedron with a dark matte obsidian texture reflecting a dull, oily sheen. The scale ratio minimizes the human figure into a minute speck against the structure's massive vertical facets. Shot on a wide-angle anamorphic lens with deep depth of field, keeping both the cracked texture of the salt ground and the top of the polyhedron in sharp focus. Color palette restricted to industrial monochrome: deep slate greys, matte carbon black, and muted sandy ochre dust. Wide-angle sci-fi film still, production concept art plate. Lens flare, glowing neon lines, high-contrast cinematic bloom, motion blur, vignette, watermarks, extra background figures, organic landscapes.
