Very nice! The only critic and the most major for me is the saber sounds.

You must consider that the clashes and hums are not placed randomly in any star wars movie.

Think a music/rythm harmony behind them and see how it works with the music or editing pacing.

This is the most common mistake in the sfx rebuilding and especialy saber sounds and blasters.

You can listen the same effect again and again with no purpose to add a variation to the whole feeling

I remember an episode in clone wars that obi and grievous are fighting and i was amazed that they used new twisted saber hums and clashes that added into the fight.

Take your time to see how sfx works and do your best :D
