Here is my process for 
Atlanta Magazine for an article about how kids who get time to play during the day do better in their academic work.  THAT'S why I like kickball on the weekend.  Now I know.
I started with the sketch below.  But the little dude was just too weird for editorial work, I guess, because the art director asked if it was a frog.  HA!

So I ended up with this guy.  It is inked by hand and colored in Photoshop.
