My favorite is the drawing I did of my family portrait. I laugh when I look at it because, I made it by taping two pencils together and then drawing the composition in a caligraphy style. It created a ribbon effect and since the ribbon is one piece it bespeaks unity and togetherness.
Also are some Bargue copies, a landscape, a doodle, a cross and a cloud study.
The ears were scanned from my sketchbook and you can see through the page the image of the five ears underneath. It's a powerful scanner. It's like an xray machine.
