When Luke and Vader are talking on the dock for the AT-AT, consider having a faint sound in the background of the AT-AT walking away. It’s a great personal conversation between the two and the way the troops walked away it feels like they are just hanging out in the open AT-AT. You’d have to remove the head of the walker in the very last shot of the scene.
Also, I know some think Revisited shouldn’t change to match the prequels, but when Vader says “Obi-Wan once thought as you do”, is a glaring discrepancy. Obi-wan never once gave Anakin a chance to turn from the dark side. It would be so much better if he said, “Your mother once thought as you do,” because Padme really did ask Anakin to leave with her.
