We had an excellent model a few weeks ago- about 100 years old, very interesting to draw, but alas I was doing really poor work that day and didn't do him justice at all.
This week I did a little better; still not great, but here it is. Again, the model was good, beautiful, Ruebensesque, and tough as old shoes. Really, I don't know how they hold those positions.
Here are two drawings from the same pose, one in pencil, one in charcoal.
