Main ideas: Creating a happy face and playing with colours. (Note the colour map on the right top corner of the picture.) Every piece of leather on the boy's cap has a different colour and even the shirt and pants have different shade of white. At first this picture was only black and white but I'm glad I coloured it. Drawing this was really fun, especially the hairy vest! Don't know about the facial expression, maybe I should have searched for a model.
Then the story: He's just a farmboy who had to leave his home. Others made fun about his clothes and it made him sad, but then he saw a travelling jester's show and it made him happy again.
