Just a suggestion... If you plan on continuing to make these unofficial artwork files... it would be nice if you created a small database of these uploaded on your personal website to make it easier and more organized for people to browse and download them. Because if you just keep them on this thread, they can easily get lost and/or forgotten.
I'm not sure if you have a personal website or not, but now days, many people have some kind of personal website/blog or whatever.
Or you could upload them to a file sharing website like https://mega.co.nz/ and then share the link with everyone so we can bookmark it.
