When it comes to the opening scene, you have the right idea but the audio is rough which makes the cuts seem jarring. I like the scene where the old man says “invasion” but in order to make it a heavier line I would leave a 1-2 second pause before he says it and when he does say it, cut to Queen Amidala and hold the shot there for a few seconds as the music builds. Afterward you will see the army going to toward the city/palace rather than the forest (this shot: http://vignette4.wikia.nocookie.net/starwars/images/0/0b/Trade_Federation_Droid_Army.png/revision/latest?cb=20140622175536) and save the forest sequence for when Qui-Gon and Obi-Wan meet Jar Jar.
I can easily do that, since the music is originally on Amidala in the movie
If you aren’t already, I strongly recommend editing with 6.1 channel audio, it will make things move along much more smoothly and moving lines around will be much more seamless.
I’m not sure what that is, but I will definitely look into it!
