Prompt

Cinematic natural realism: a turquoise glacial river winding through volcanic gravel in a high alpine valley beneath distant snowfields, with a diagonal leading line from the foreground riverbank toward a vast mountain horizon. Crisp early morning sunlight casts long valley shadows across an expansive, invigorating landscape, rendered in ice blue, charcoal, and muted ochre with controlled visual noise, no text, watermark, logo, border, or interface elements.
