About this clip
Generated with Wan 2.7: a pink flower bud in a white vase on a sunlit windowsill.
Look at the petals, the surface of the vase, and the sunlit shadows. In ten seconds the bud opens into a full pink bloom, and then the petals fall onto the windowsill, as in a time-lapse. Notice how the flower's shape and the shadows on the sill change.
