I'm very interested in these edits, they have a lot of good ideas. However, I don't like the idea of Dooku having a purple lightsaber. Not because I think it needs to be red, I just hate purple lightsabers! If it was up to me, I'd have rotoscoped Windu's to blue and Dooku's to green. I understand that you wanted to have a different lightsaber color for the duels, but the Obi-Wan/Vader duel works fine with the same lightsaber color.
It's not a deal-breaker, it's just that the purple lightsaber was one of the little things about the PT that irked me so much.
I do like, however, that you only have Yoda use his lightsaber once (the Order 66 scene), and the way he uses it in that scene is perfect - short, efficient, and not flashy at all. Perfect. Well done on that.
