The idea behind this prompt is to make yourself a "certificate" to acknowledge something you're good at. It doesn't have to be art related. I struggled a bit with this because I get the whole self-empowerment thing and I applaud it. On the other hand I would NEVER want anyone who has spent their time, money and blood, sweat and tears getting a proper designation for anything to think I was making light of all their hard work. I assure you I am not.
That being said, in the spirit of fun that was intended and by the powers not vested in me whatsoever, I present you with my "collage licence".
