I laughed out loud when Qui-Gon starts telling Shmi about the parts he needs. Anakin asking his mom if she's an angel was good too, and well-executed in terms of audio.
After Ani says, "Isn't he great?" with regards to 3PO, is there a line of dialog you could give Padme in response (something like "I don't know" or maybe cut out the "I don't" part and just have her say "no")?
