Drawing on the right side of the brain

I have been doing art lessons in my home for quite a few years now and one project which I have done with a few of the kids has been a favorite of mine.  I love the book, "Drawing on the right side of the brain" and in that book it talks about drawing using the right side of your brain and drawing something upside down to train your brain to draw something as you see it instead of drawing things the way we think they should look. There is a picture of JFK in the book which I have used to have the kids draw from.  They draw it upside down and I coach them all along the way as they draw.  Here is a brother and sister that just finished them last week.  They took about 4 hours to complete them.  I had them draw a picture of a face before they started so we could see the progress.  I think they did an amazing job!
