After some experimenting, and after some suggestions over Mint forum, I came up with this one as my final solution for Isadora CD/DVD cover... As you can see, there is now official Isadora artwork set as background, and some more grey beside green pallete. There are 4 CD/DVD cover variations, (32-bit and 64-bit) and 4 CD/DVD label variations (32-bit and 64-bit).
