A medium shot from a side angle depicts a young girl and a colossal white whale gliding together through a surreal, shimmering expanse where the ocean merges seamlessly with the sky. The girl, with long flowing hair and a simple white ethereal dress, clings gently to the whale's smooth, pearlescent skin with her small hands, her expression one of pure wonder and serenity. The massive white whale swims gracefully through the air, its enormous fins rippling like silk, leaving a trail of luminous bubbles and stardust in its wake. The environment is a breathtaking fantasy landscape where floating islands and distant clouds are reflected in a mirror-like crystalline sea that stretches to the horizon. The lighting is soft and celestial, featuring a palette of iridescent blues, pale violets, and shimmering golds, with a dreamy atmosphere enhanced by floating light particles and a soft-focus depth of field that evokes a sense of infinite peace.
