Ok, it's time to face facts, I'll never learn how to color if I don't start to practice. And I thought it was time for me to learn how to color on the computer. So... I've started on level one. A kid level. Easy and slowly. This was my first testpicture.
I try to look at how children's book illustrators work (since that's my secret dream job) and they often work in many layers and use a basic sketch that they color.
