It can be adjusted slightly further but I think it's now hugely improved. The skin tones were far too red at times in those portions, they almost looked like boiled lobsters. I think the adjusted pics not only look far more faithful to the film's original presentation (which is the most important thing) but also more aesthetically pleasing in general because they look more natural. Alec Guinness and Mark Hamill were two of the whitest dudes ever to have lived, it looked off when they were maroon. Those Vader pics where you tweaked the brightness and recovered details in the black portions around his helmet base and cape that were once crushed out are good shit too.
