I made an art challenge called the four color four animal challenge. You pick four random colors from your selection of markets or whatever and then you use a random animal generator to generate four animals. You choose one of the four animals and draw it with the colors chosen. You are only allowed to use those four colors as well as a black liner and white.

This was my first one. It's a civet. Still not sure if a civet is a cat or rodent. Open for name suggestions for the civet.
You are welcome to do this challenge and tag me in your finished picture.
