It looks very , very professional, I am really impressed. The cantina music isn't really my cup of tea, but that is purely personal, I think overall it is an amazing clip.
However the voice for Anakin sounds really amateur hour. It sounds exactly like a person 'putting on a voice' and talking slightly below their normal register. It really sounds flat and hokey to me. I have no problem with it not being Hayden's voice, I only saw Sith once, and can't even remember vaguely what he sounds like, but that dubbed voice sticks out like a sore thumb in what is otherwise a really professional piece of work. I don't think it needs to sound like Hayden (he talks very woodenly anyway from memory) but does need to sound real.
It sounds exactly like when I use friends for short films rather than grabbing actors, they always seem to hit that flat kind of sound, whereas actors, even local dodgy stage ones don't seem to do that. I tend to get the local performing group to do voice ADR even if I don't use tham as actors.
The only people who are worse in my experience are 'voice over' people, they make truly horrible voice actors!.
I hope you are putting together a making of or an audio track describing what you did, how and why, it would be great to hear.
Great Stuff!
