The ship, detailed with tattered sails and intricate rigging, sails majestically under a luminous moonlit sky. Below, the mysterious depths are dominated by the fearsome Kraken, its dark tentacles entwining around the cake's layers, depicted with lifelike textures and shadows. The scene is set within a breathtaking and artistically crafted universe, where each element is rendered with hyperrealism and photorealistic detail. Dramatic lighting enhances the depth and dimension of the scene, highlighting the intricate designs and creating a captivating depth of field. Using Unreal Engine, the diorama achieves an astonishing 8k resolution, capturing every detail of this fantastical and immersive world.
