Prompt: Create a surreal and mystical A3 portrait-sized image of a sunset scene. Envision a fantastical horizon where the sun sets with vibrant, otherworldly colors. The water in the foreground should reflect these surreal hues, creating an ethereal atmosphere. Enlarge and center a mysterious and enchanting island in the middle of the scene, devoid of any figures. Infuse a sense of magic and mystery into the overall composition, and ensure that there are no trees present. Craft this dreamlike scene within the dimensions of an A3 portrait canvas.\"
