Joyful girl riding a colossal seahorse underwater

A 12-year-old little girl with bright orange water wings and a joyful smile rides on the Head of a colossal, shimmering seahorse, sitting high on the head, with the Legs behind des Ears of the Seahorse, gliding through a crystal-clear, sunlit ocean. Her hair floats weightlessly, and bubbles trail behind them as schools of fish swim past in awe. Coral reefs and underwater ruins stretch far below. The seahorse is majestic, covered in pearlescent scales with delicate fins like silk banners. Magical realism, high-detail underwater lighting, dreamlike colors, weightless atmosphere, childlike wonder meets oceanic fantasy
