Vivid sunset sky with contrail over dark silhouetted landscape

A wide shot captures a dramatic sunset over a dark, silhouetted landscape. The sky is a vibrant gradient of deep oranges and reds, with wispy clouds catching the last rays of light. A single contrail streaks across the upper right portion of the sky, with a small, bright dot, possibly a planet or star, visible above it. In the mid-ground, a low, dark hill is topped with a structure that appears to be a fortified observation point or a small castle. A flagpole stands prominently on the hill, with a dark flag unfurled against the fiery sky. The setting sun, a brilliant semicircle of white light, is just touching the horizon behind the hill, casting a radiant glow. The foreground is almost entirely black, obscuring any details of the immediate surroundings, though vague shapes suggest trees or buildings. The dark, low horizon line separates the silhouetted land from the intensely colored sky. The overall impression is one of a serene yet powerful natural spectacle.
