Generate a first-person perspective (POV) video of a woman in green (@Image1) flying on a sword through mountains. Real-life cinematic style. The camera mimics human eyes (no face/body shown, only the sword). Shot 1: Looking down at shoes and dress. Shot 2: Looking forward while flying. Extreme shaking and speed. One-take flow. Only environmental sounds, no BGM. Mountains are huge, character is small. Scale of sword is realistic. Camera position stays constant, only tilting up/down.
