Maybe you could add a sound for the skin morphing, like playing with the pitch of leather getting wrinkled. I looked up the scenes of Indy on youtube and it sounded like something like that was going on.

On the subject of changing pitch, I was wondering if you could do it with Yoda’s voice. I think his voice seems to sound brighter than in the OT, but that doesn’t make much sense when you’re aging ten times slower than a human being.

Also, I don’t know if I like having Duel of Fates playing when Anakin uses the speeder bike. I thought that you could maybe insert this version of Anakin’s theme starting at 1.37: https://www.youtube.com/watch?v=WUC7MgkOgKA
