Twilight Desert Dunes

An expansive desert landscape at twilight, with rolling sand dunes that glow with a soft, golden light. The sky above is a deep, rich purple, dotted with the first stars of the evening. The dunes create a rhythmic pattern, their curves highlighted by the setting sun. In the foreground, a lone cactus stands silhouetted against the colorful sky. The image is hyper-realistic, focusing on the contrast between the warm tones of the desert and the cool hues of the twilight sky.
