Scene opens with a cinematic aerial shot slowly descending toward a calm, tropical river at golden hour. The sun is low on the horizon, casting warm orange and pink hues across the sky. The river is surrounded by dense jungle with tall palm trees, hanging vines, and distant bird calls echoing. The camera glides just above the water’s surface, capturing soft ripples, floating leaves, and golden reflections. Gentle ambient nature sounds – insects, distant howler monkeys, the occasional splash. As the camera reaches the center of the river, it slowly tilts downward and transitions seamlessly below the surface. Crystal-clear turquoise water reveals an enchanting underwater world. Shafts of sunlight break through the surface, creating dancing light patterns on the riverbed. Small tropical fish swim gracefully between smooth stones, aquatic plants, and sunken roots. Tiny bubbles rise, and the water feels tranquil and alive. Everything is rich in detail: textured rocks, floating particles, gently moving algae. The atmosphere is peaceful, magical, and immersive.
