Things I'd like to see tweaked:
The Tatooine Millenium Falcon escape scene. The star destroyer the falcon flies by looks so odd. Stiff and out of place.
The added planet where the Death Star originates from. Looks good but doesn't mesh with the rest of the CG very well.
Tweak the added TIE Fighter scenes so the blend better.
Add the other solar panel(left) to the TIE that Luke destroys saving Biggs.
Fix the red TIE Fighter in the Battle of Yavin (seen in the middle of trio flying away in distance).
Things I'd like to see added:
The Death Star slipping into hyperspace from planet of origin.
Porkins not dying.
