I quite like Threepio's reaction to Luke's presenting the droids to Jabba as a gift. It does work, and we have to bear in mind that many edits seem strange as we know these films so well that we expect to see what has always been there. On the other hand, one might argue that a more dramatic reaction to the news would be more in character for Threepio.

The reaction to the thermal detonator is clever, but a little too quick for my liking. You are absolutely right about the Muppets-style reaction shots, but I think that unfortunately the best of the bad bunch might have to stay. Could you keep Boba Fett and change the music?
