From 2002. Chippusu-neko is an old anime catguy I used all of four times, not counting here. He was to be self-employed as a masseur; his shop would have been called You Need To Be Kneaded or something like that. Chippusu’s head shape was based on a Reuleaux triangle.
Mechanical pencil on paper, scanned, colored with Gimp. I think this was my first real use of Gimp.
