Okay, just got this downloaded and it looks really good!
In particular, the first part of the first Echo base scene, much of Dagobah, Arrival at Cloud City, Han in Carbonite, and the Rebel Fleet all looked especially good. The final scene in particular looked phenomenal.
There is an issue which plagues the grindhouse edition, and that’s the greenish highlights. Note how the core of Luke’s saber is often green, as well as any metallic surfaces which are in bright light. The best way I found to combat this was to hue shift everything from the greens into the blues, then selectively return the unproblematic hues to their original state. If you were able to adjust only the highlights, that may be even better.
