"First I choose a pic from web (Facehunter or Sartorialist), then I draw and then I read whatever comes to my mind about that person drawn on my sketchbook. It's fun!"
One of our favorite past times, or ways to pass time, in an airport, restaurant, hotel pools etc, is to create stories behind strangers that we see. I agree, it's great fun. You should try it out sometime. Also, I love this gal's art.
