I recently viewed a Scott Burdick DVD where he demonstrated painting with powdered charcoal and water on illustration board.  I was enthralled, it seemed like a great blend of painting and drawing.  To create "Relaxing" I laid an initial wash with the charcoal then loading the brush with more charcoal I massed in the figure and background.  When it dried I lifted out the light areas with a kneaded eraser then finished by using a stick of charcoal to add lines that were important.  This is one of my first attempts at this blend of drawing and painting.  Should it be called a drainting or a prawing?
