PROMPT:
Create a photorealistic image in the playful category featuring a whimsical underwater scene. In the foreground, depict a group of happy, anthropomorphic sea creatures - a smiling octopus, a laughing fish, and a carefree seahorse - playing a lively game of musical instruments made from colorful, glowing coral and shimmering seashells. Use vibrant colors to bring the scene to life, with a focus on blues, greens, yellows, and oranges, minimizing the use of pink. The lighting should be warm and inviting, with soft, diffused sunlight filtering down from above, illuminating the characters and their instruments. Add some subtle, shimmering ocean effects, such as sparkling sea spray and delicate, undulating seaweed. Make the overall mood joyful, lively, and full of energy, as if the viewer has stumbled upon an impromptu underwater jam session.
