Wow so many changes. Hard to keep track of them all. A brief cut list perhaps?
Very clever combining of both Dooku force attacks on Kenobi and you nailed the implication that an external blast causes the platform to collapse. Colour work is great as usual but is the shot of Palpatine saying "We'll never make it" still supposed to be blue? The radical cutting of Dooku's death is a shock at first but after a few watches, it works beautifully.
