There is something you can add that may help it sound more natural. When Anakin speaks there is a distinct lack of ambient background noise, most noticable in the argument scene. You can here some noise when Padme speaks, mainly her chair creaking, but when Anakins dialogue begins it ends abruptly. If you could add some foley, or something like that, then it sould enhance the dialogue and help the new dialogue blend in with the original track. But you are definately on the right track. Amazing job. I just can't wait to see the final product.
