Remember this from Primary and Intermediate school? Take a white crayon and draw a design on a sheet of paper, then go over your design with watercolor paints. Although this technique seems a bit primary - does it hold value for a more "refined" style of art? Of course it does! I want to challenge you to try and take this "basic" style of art and create something more aesthetically mature like the image below.
So do you have it in you? Test it out and have fun!
Keep those pencils sharp and ideas fresh
