I don't plan to draw like this too often. I like a loose, painterly result, and I tend to overwork and over-render my longer drawings. But they are a powerful learning tool, especially combined with shorter drawing exercises. Each approach teaches something different. Artistic cross-training.
Some comments on these drawings...
Model movement is a challenge during longer drawings. You can see movement in Jonathan's right leg, below. It started out lateral on the first day, and moved to center on the second day. If my anatomy knowledge was stronger, I could have pulled off the drawing. I left that twisted leg as a reminder to review my leg anatomy. Model movement is part of life drawing. If you're a figurative artist, you learn to work with it.

If you are a student of figure drawing, get Henry Yan's beautiful book on the subject. Full of examples of both short and long charcoal drawings, using a variety of techniques. A good reference book.
