I watched all three of your prequel edits recently. They felt seamless (except for perhaps that day-to-night shot in EpII) and as if they were actual replacements for the movies. Wish I had something like it to swap RotJ out with.
To chime in on the conversation above, I did miss the funeral scene (the music mostly) - but only because I knew about it previously. I think your revision here works well enough in concept. She looks clearly distressed in that scene (I’d imagine she wasn’t super keen on giving up Luke), and shortly beforehand the droid states that she won’t last very long. It just adds a nice extra lie from the Emperor to complete Vader’s transformation.
