Worm's-eye view of sunlight through a giant tree canopy

Photorealistic cinematic nature film, 10 seconds, 16:9, worm's-eye view / looking straight up from the base of a giant tree, as if the viewer stands right beneath it. Very thick grayish-brown trunk, rough cracked bark, forming a vertical anchor in the lower-center that narrows upward (correct perspective convergence). Almost-black dark branches radiate outward like outstretched arms, in 16:9 they stretch fully left-right forming a symmetrical mandala/dome pattern. Lush fresh green and dense dark green canopy overlapping; gaps of white-blue sky and sun backlight create beautiful god-rays / light shafts, and edge leaves glow translucent. One very slow orbital rotation (like turning your head to look up) plus leaves swaying in wind plus shimmering god-rays, no cuts, no dizziness. No horizon, no ground, no people, no animals, no text. HDR, cinematic grain, anamorphic bloom. Tone: majestic, immersive, calming, standing beneath a living green tree.
