A few suggestions:
- This would impact many shots, and many of them are blurry shots of Han running, so this could be very difficult to do convincingly.
Dak's helmet - You did a great job with color correcting these in A New Hope, but they did it again in Empire:
Snowspeeder markings - there are numerous examples of this, but this images are indicitive:
I played with adding an orange stripe to the front of this speeder.
Luke doesn'r really look like he's in this shot. The lighting doesn't match, the registration was poor, and there's no shadow effect under him.
