I've added the new version of the "LeChuck's Revenge" artwork (based on @kiddomanteca's amazing scans) to the thread, replacing all the other versions (which are still available on the GoogleDrive though). The bump in quality is massive. Just check out these comparisons of the new scan with my old v1 and v2 versions:
For painting out the logos and extending the edges, I again resorted to training my own AI model, which in turn tried to apply the style and detail of the new scan to my (textless) v2. I then used this to paint out all the unwanted parts, keeping as much of the new scan as possible.
