For the Github Repository Homework, I uploaded an old drawing I did of Darwin Watterson from The Amazing World of Gumball.
What I intend for people to do with the drawing Is to observe it and use it for their own purposes They can share it, edit it, critcize it, or use it as a reference.
I choose the GNU GPLV3 because it is a drawing, and a not so good one at that. I doubt most people would even want to claim it was their own doodle, but if they do it's there to say otherwise. But other than that it allows people to use it as long as I'm credited. That's good enough for me considering I don't even draw that often.
