Is there any way to make the Jedi duels look more like they did in the PT? Nothing drastic. Mabey have them hold on to the saber with 1 hand or something.
Also, I would add CG buildings on Endor because I never bought how the Empire had one little room controling things. Make it look intimidating.
I think there needs to be a bigger battlefield. Show different places on Endor and do some airial shots of Endor to make the battle feel larger.
