Snowy Ridge Giant Spherical Survey Machine and Explorers AI Image Prompt

2:3 vertical, sci-fi scene simulating real snow mountain expedition photography. On a narrow snow ridge stands a spherical survey machine dozens of stories tall; its huge silver-white spherical shell occupies most of the upper frame. The front has deep black concentric circular optical apertures, with inner lenses receding layer by layer into darkness, and only a tiny white reflection point at the center, like a giant eye silently watching humanity, emitting no light beam. The shell has finely detailed armor plating, a few circular vents, thin antennas, and maintenance ports. Its only black lettering is “GenVizu”; no other text or numbers. Below the shell are a heavy black exposed frame, cooling system, hydraulic structures, and two extremely massive tracks; the tracks bite into the snow along the ridge, with a clear sense of structural weight. The white shell is partially frosted and slightly weathered, with snow in black seams. Wind from the right kicks up fine ground-hugging snow; do not use heavy fog to obscure the machinery. In the foreground, two adult explorers in dark alpine protective suits, carrying equipment packs, walk away from the camera toward the machine, holding trekking poles and small detectors. Each person is no taller than one-tenth of the frame, steps cautiously, footprints extending along the snow ridge, appearing small and exposed. Distant mountains fade into pale air; a tiny drone serves only as a scale reference. Low-saturation cold gray-white, realistic scattered daylight, natural dark shadows, credible lens perspective, and fine snow surface texture; an unknown, silent, oppressive documentary feel. No combat, no heroic poses, no other text, watermarks, concept illustration, or plastic render feel.
