OK, just finished it. Looks pretty good, but there were a few things that stood out to me.
At 2 minutes in, just after the intro text, the camera pans down and we see the star destroyer. I think there is a Despecializing effect going on there because the ship seems to be cut in half and each half is wobbly.
Between 0:05:00 and 5:30 - the key light on Han and Princess Leia seems a bit too hot and is blowing out details.
At 13:00 and 13:11, the long shot with the force ghost, there is an obvious special effect matte that is very visible. (perhaps that was always the case?)
And finally, this is a bit controversial, but perhaps you could clarify exactly why you decided to use GOUT upconverts for the speeders and the initial scene of the Empire's fleet at 19:36? I know they were recomposited for the SE, but so was everything in ANH and that didn't stop you from using those recomposited shots there (the opening battle between the star destroyer and the Tantive IV for example).
