Watermelon and bowl

oil on canvas paper 5"x7"

It was  required, in the DPW challenge of this week, to paint after a picture, upside down.In fact, most of the time, I used to do that;I learned this technique, a long time ago, in Betty Edwards's books, and I like it.When I am not sure about my drawing, I turn my painting for checking it, and  go on for a while, upside down, I find it funny.
