Pixel artwork with a green monochromatic palette

pixel artwork with a green monochromatic palette depicting a surreal underwater and above-water scene. The upper half shows a ship with sails and a starry sky while the lower half reveals a treacherous underwater landscape with jagged cliffs ruins and a large coiled tentacle in the foreground. Light from the surface illuminates the underwater scene creating a gradient from dark green at the bottom to lighter green near the surface. The composition uses a split-level perspective emphasizing the divide between the two worlds. Textures include the rough rocky underwater terrain and the smooth cloudy sky. The mood is mysterious and slightly ominous with a dynamic interplay between the calm surface and the chaotic underwater environment. The use of light and shadow enhances the depth and three-dimensionality of the scene.
