Looks like there are three separate things here, photos of completed papercraft projects, digital papercraft templates, and drawings of characters making papercraft. The tag should be split up along these lines. Completed papercraft photos is the only one that would qualify for implying unconventional media.
"Unconventional media" is a tag I made up that was meant to be a catchall term for anything that's not digital or traditional media. I called it that for lack of a better name but I'm open to changing it if anyone has any better ideas.
