Nice job on the music of the factory scene indeed!
I made a little edit of this droid factory scene few months ago, here's the link again:

I tried to keep 3PO and R2 but cutted some silly parts and changed the order of the scenes.
(3PO still looses his head cause I tried to make the scene "better" without changing any element of the story)
