While yes, there may be a bit too much yellow (in the star destroyer, mostly), I think this might be about the best attempt yet.
I don’t think that there’s any getting away from the yellow in the star destroyer without making Tatooine too blue, unfortunately.
Unless one were to mask around the elements to adjust the colors independent of each other, which is commonly done in situations like this in professional restorations, but may go against the spirit of this project.
