RE the Wampa scenes -

If the issue of the shoulder vs. elbow cut on the arm could be resolved, I'd suggest to remove all SE Wampa additions with the exception of the ONE shot post-amputation after Luke himself sees the creature. That way you get a good look at the Wampa without ruining the suspense of the scene - we only see the Wampa in its full "glory" after Luke does.

I'm fine either way, just thought it'd be a compromise - but, again, this is your edit, Ady, and if you don't like it, it shouldn't be there.
