A breathtaking hyperrealistic digital painting depicting a split view of a tropical lagoon. Above the waterline, a weathered, three-masted sailing ship with dark wood and tattered sails floats serenely between towering limestone cliffs covered in lush, vibrant green foliage and palm trees. The sky is a brilliant blue with fluffy white clouds, and distant misty mountains are visible on the horizon. Below the waterline, a teeming coral reef explodes with color and life. Various species of coral in shades of yellow, orange, pink, and green form intricate structures. Schools of brightly colored tropical fish, including yellow and black striped fish, dart amongst the coral. The water is crystal clear, allowing for perfect visibility of the underwater scene. Sunlight penetrates the surface, casting dappled patterns on the sandy seabed. The overall mood is one of vibrant natural beauty and peaceful isolation. The scene should evoke a sense of wonder and tranquility, capturing the intricate details of both the terrestrial and marine environments in a photorealistic style.
