Harmy,
I finally finished watching the first part of the workprint. Everything looks good except for the star warping issue I mentioned during the flyover.
About the colors, I see there's been some considerable discussion about that, and you plan to pull back on the reds a bit. The comparison bkev posted is a good example of the monochrome look I'm talking about. The shade of Luke's hair compared to his flesh tone is too similar to my eyes. Add in the slight brightening from recovering the blacks, and the overall result looks "sepia".
Again, remember that I'm no color expert, and I don't remember what this looked like theatrically.
I look forward to the next 40 minutes :D
