A hidden natural hot spring pool surrounded by massive ancient banyan trees, steam rising from crystal clear turquoise water, weathered stone tiles and moss-covered rocks, dozens of vibrant hummingbirds and tiny tree frogs near cascading mini waterfalls, soft morning light filtering through dense aerial roots creating warm volumetric rays and ethereal mist, rendered with Unreal Engine 5 raytracing and PBR materials, reimagined as hand-painted Studio Ghibli animation with visible brushstrokes, warm gouache color palette, cinematic composition with strong natural perspective and peaceful atmospheric depth
