An ethereal underwater oil painting of a beautiful mermaid with long, flowing pink and white hair, surrounded by vibrant coral reefs and colorful tropical fish. Her expression is serene, her face delicate and dreamlike, with eyes gently closed. Her upper body is adorned with a detailed, flowing translucent gown, decorated with intricate floral patterns, while her shimmering green mermaid tail cascades gracefully into the scene. The ocean is alive with vivid aquatic plants, glowing coral in hues of pink, purple, and orange, and exotic fish swimming around her in shades of yellow, blue, and red. Soft rays of sunlight pierce through the water, creating a magical, diffused glow that highlights her hair and the underwater details.
