Act as a steampunk illustrator with 10 years of experience in creating detailed, atmospheric scenes. Generate a highly detailed DALL-E image of a majestic steampunk airship soaring above a rugged mountain range at sunset. The airship should feature intricate brass and copper machinery, billowing smokestacks, and oversized propellers. The mountains should be [snow-capped/volcanic/jagged], with [misty valleys/glowing lava flows/ancient ruins] below. The sky should be filled with [dramatic clouds/aurora borealis/flocks of mechanical birds], casting a golden-orange hue from the setting sun. Include small details like [fluttering flags/leaking steam/glimmering lanterns] to enhance the realism and immersion of the scene.
