I think you should, however, remove that fanfare before the cut to Palpatines office... just start with the "dun" with the subdued music... or maybe find some way to cut to it... maybe place that unused shot of the outside of his office at sunset from the deleted scene or something...
Otherwise kinda cool. I love the subtle editing of the conversation with Anakin.
As far as the actual fight goes I like it... the sound is rough but that can be fixed... the use of Darth Vaders music there is ok... but there are better choices...
I like it though... overall it's good
