Highly detailed 3D model of a classic zeppelin airship with a long, streamlined hull covered in stitched fabric panels. Include intricate details such as the gondola beneath the hull with visible windows, propellers, and engine compartments. The model should feature metallic support frames, ropes, and small access ladders. Add subtle weathering to the fabric and metal surfaces. Set the zeppelin against a soft cloudy sky, with realistic lighting highlighting its majestic and vintage design.
