*The obviously human guy posing as a Jawa at the end of the purchase of the droids scene.
*The cord/battery pack up Luke's sleeve when he first ignites the saber and waves it around in Kenobi's house. I know it's quick and most don't notice, but once you do notice you never don't again. You said this was difficult, but it seems like an easy fix compare to the other amazing things that were done!
*A couple of shots during the saber duel you can still see the cord near Kenobi's sleeve. This should be painted out, maybe using elements of Kenobi's robe as it was in others shots.
Thanks so much for the amazing work and this edit has made my year so far!
