Heh, I was actually also going to post those exact tunic shots that you've just shown on the left and right of your example adywan, as well as a few more that come afterwards, but my post was already quite lengthy.
I'll go into the rest of what I think when I get a little more time, but let's just say for now, that the shot of Luke with his arm in a sling (when he's sensing Vader as the Falcon nears the Executor) is showing skin too, and looks similar to Luke's tunic shoulder when his hand is cut off.
Thanks for clarifying your thoughts on the Vader swipes at the doorway too, and very much looking forward to your anniversary clip later this month. :)
