A hidden geothermal hot spring deep in an untouched tropical jungle at dusk, massive clouds of warm mist rising from crystal-clear turquoise pools surrounded by enormous ancient tree roots and towering ferns, exotic resplendent quetzals and tiny iridescent hummingbirds perched on moss-covered branches, luminous bioluminescent fungi glowing softly on decaying logs, soft volumetric sunset rays piercing through dense canopy creating warm golden god rays and prismatic light dancing through mist, rendered with Unreal Engine 5 raytracing and PBR materials, reimagined as hand-painted Studio Ghibli animation with visible brushstrokes and watercolor texture, warm amber and deep emerald green gouache color palette, cinematic low-angle composition with strong atmospheric depth and mystical hidden sanctuary atmosphere
