Create an Ancient Viking Longship in a Stormy Sea

Act as a historical illustrator with expertise in Norse culture and seascapes. Generate a highly detailed, cinematic-style image of an ancient Viking longship battling fierce waves during a violent storm at sea. The scene should include [Towering waves crashing against the ship], [Rain and lightning illuminating the dark, brooding sky], and [Viking warriors clad in traditional garb, gripping the oars and shields tightly]. Ensure the longship is meticulously accurate, featuring intricate carvings and a dragon-headed prow. The atmosphere should evoke tension and drama, emphasizing the raw power of nature and the resilience of the Viking crew. Use a [dynamic composition] to highlight the movement of the ship and waves, with a color palette dominated by shades of deep blue, gray, and flashes of lightning white. Add subtle details like sea spray, soaked sails, and the crew's determined expressions.
