I have one little tiny suggestion though. The only part I found a bit jarring at all (and this may be because it was edited for the trailer) was when Obi-Wan ignites his lightsaber in the upright position and in the next shot he's holding it more paralell to the ground. I think that if you added a lightsaber motion whur sound off screen in between these shots (during the vader shot) it would feel like he moved the saber when we weren't looking. Just a thought. It was so cool, very well done.
