거대한 속이 빈 나무 안의 숨겨진 숲 생태계

A secret ecosystem inside a giant, hollowed-out tree. The wooden interior walls are covered in glowing moss and fungi, with small ferns growing from cracks. A central pool of clear, still water reflects the starry sky visible through a hole in the roof. Whimsical yet plausible ecosystem, blending Miyazaki-inspired imagination with photorealistic detail of wood, water, and bioluminescence. Cinematic, magical, and serene atmosphere.
