While the first SS shadow shot needs to be lower on the ground and flatter to match the AT-ATs shadow, the scene at 0:32 doesn't have a shadow for the SS at all! On 0:35 -0:36, should there be a SS shadow on the AT-AT legs? Also could use a mountainous background (and maybe a squad of SSs flying in the rear) for 0:50.

And as far as the transparent cockpit, it looks like Ady addressed this already: http://www.youtube.com/watch?v=qjEnjYe2Dbg&feature=related
