OK, finally downloaded the workprint, and here are my rough notes about what I saw. I mainly looked at color consistencies/inconsistencies. I listed the approximate timecodes for the events.

4 min. - Stormtrooper beige color

6:50 min - stars in the escape pod shaft flickering? Is that correct?

"No one to stop us this time" - Vader's friend slightly brownish

12:50 min - bluish Sand Crawler lights

14:45 - too bright, washed out sand color

16:35 - also too bright?

20:03 - color levels/Luke's hair and skin tone

20:45 - squarish hologram "shadow" behind image

23:13 - bluish table - should be white? Luke's clothes are also a bit blue

24:50 - odd color switch between shots - goes from orangey in the Binary Sunset scene to greenish in the next shot

29:30 - Odd color levels - Obi-wan very pale/brown, compared to later in the shot or at his home

35:12 - Color of admiral different from later in the clip

Also, Princess Leia differently colored in detention cell; may be because of the whiter lighting as opposed to the reddish lighting on Tantive IV.

The good things I noticed:
Awesome clarity of the Star Destroyer in the beginning shot/tractor beam shot. Did you use the BD as a source? Also, no "ghost Luke"!
