Silhouette of Bus on Austrian Mountain Switchback

Indigo twilight washes the sky in deep violet gradients above a steep mountain ridge. A dark bus silhouette navigates a sharp hairpin turn carved into the rock face. Below the road, a thick layer of low-hanging clouds fills the valley, appearing as a smooth, white expanse that swallows the terrain. The vehicle's rear lights glow as faint red points against the encroaching darkness. Bare branches of a few resilient trees line the roadside, their thin limbs stark against the fading light. The asphalt road curves sharply to the left, disappearing around the bend. One metal guardrail runs along the outer edge of the curve, catching the last faint ambient glow. The rear bumper of the bus rests just above the white cloud line.
