Act as a seasoned concept artist with expertise in maritime fantasy. Create a highly detailed DALL-E image prompt depicting a [17th-century pirate ship] locked in a fierce battle with a [gigantic, multi-tentacled kraken] amidst [turbulent, storm-churned waters]. The scene should be dramatic and dynamic, with lightning illuminating the chaos. The pirate ship should have tattered sails, cannons firing, and crew members scrambling on deck. The kraken's tentacles should be wrapped around the ship, with one tearing through the hull. The ocean should be dark and foreboding, with towering waves and foam. Include subtle details like [glowing bioluminescent markings on the kraken] and [floating debris from the ship]. The atmosphere should be cinematic, evoking a sense of epic struggle and danger.
