Not sure if this is what you were trying to point out at the end of your post IF (when mentioning the vanes), but it looks as though the vane Luke is hanging from changes position between these shots relative to all the other vanes. Whereas all the other vanes seem to be static between these shots, the one Luke's on moves. The difference in position can't be attributed to the camera moving, as all the other vanes appear in the same position in each frame.
Sorry if I'm just repeating what you said, but it's a noticeable error, so I wanted to be clear about it.
