Cloud river flowing uphill vertical scene

A colossal ribbon of clouds flows uphill through a towering canyon, moving with deliberate, dreamlike momentum toward the top of the 9:16 portrait frame, evoking gentle wonder and quiet ascent. The scene is mist-laden and cool, with a soft cool-blue wash anchored by deeper indigo and violet accents for sculpted form, and warm golden highlights from #FFD166 catching edges to suggest late light. Surfaces read tactile and grand, with dense cloudbanks, weathered stone canyon walls, and faint crystalline mist on ledges. Foreground cloud detail resolves crisply with textured billows, while mid and background layers fall into softer haze for moderate perceived depth. The viewpoint is tall and slightly low, a vertical sweep that feels narrow and cinematic within the 9:16 crop, leaving clean negative space above for upward motion. Small, purposeful story cues include a solitary silhouetted figure on a ledge and a distant waterfall of vapor to imply scale. All visible surfaces remain free of lettering and signage, with micro-formed lines and streaks reduced to abstract patterning. Render as a matte-painting style illustration with painterly strokes, gentle glow, and controlled atmosphere to emphasize motion and scale.
