Scribble Faces

Day 4 in the Faces 101 class called for "scribble faces." I sat in a local taqueria (waiting for my to go order) and quickly sketched the people around me.  I really enjoyed doing these. The two on the left are both of my husband.  He liked the top one well enough that he made it his profile picture on facebook! The more faces I draw, the easier they become, and I've gotten lots of good ideas for different styles of faces that I could start including in my art journals and collages. In the class we sometimes draw/paint faces from live models, sometimes draw/paint them while looking at a picture and sometimes draw/paint from our imagination.  I'm not sure I have a preference yet. If you draw, paint or sketch, do you have a preference?
