I think more sound effects need to be in there. More blaster shots, gunshots, etc. (It can be lower in the mix than the song.) The clones need to have their usual laugh when they off the Jedi. Plo Kloon(?) could curse when he crashes his ship. Actually, all the Jedi could curse when they buy the moisture farm.
Falkor could holler "Atreyu!" as he and Obi Wan fall.
The Fax machine(?) could emit Artoo's various screams.
The main killer rabbit scene, where it's attacking all the knights at once might work even better.
