I'm downloading the 2nd clip now, and I'll check it out soon.
Edit: I was replying when I had some kind of power surge that made things flicker. Thought evrything was okay, and, then my computer shut down. I'm typing on my roommate's computer right now, because I couldn't get my wireless conection to come back up. I blame mynocks.

So, I watched the second clip, and I continue to love how much better of a character the dialogue replacement makes Grievous! Your cut of the duel is better, too. I especially like how you don't allow for the same kind of shot for both of G's hands getting cut off. That always hit me as bad filmmaking. I have some critiques if you will indulge me (if you won't, then just skip the rest

1) Though the insert shot cuts in beautifully (aside from the absence of Obi-wan's cloak), Obi-wan's ignition of his lightsaber for his ride up the cliff and the subsequent shut-off doesn't really seem to have any motivation behind it. He knows where Grievous is, but he hasn't decided on his tactic yet as evidenced by his thoughtfulness before he decides to jump down to face him.
2) Is there more dialogue for the Separatists which could be used? It seems odd that their voices are unintelligible while Grievous' is not. Maybe some subtitles? Not sure how that would play against Grievous's response in English, err, Basic, though.
3) Grievous's line "Mine" sounds a bit off, I think due to the difference in background tone. If you layered in some silence from your new Grievous source, it would probably play the difference down.
4) The shot where G's hand and a lightsaber is seen falling to the deck below him seemed to be trimmed too short.
5) Oh, yeah! ALmost forgot the lizard (I wish I could). Nice job with the new noises instead of the yelps. Can I put in a request for even less yelps?
