I really like it, even if it runs long. The contrast might be a bit too low but I dunno what you can do to preserve the colars and salvage some of the detail (can you bring in more yellows?).
What if he just repeats the “ship/cup/speeder” lines? Might be hard to modulate it to Vader’s voice unless you can find similar phonemes (he does say ship at least once).
Maybe he says “You’re so beautiful” as he turns to Palpatine? Or do you want serious directives and not malfunctioning memories?
