Pasteling Over

I arrived late at my drawing group today, caught behind a tractor.  The first pose had already begun. It was a ten minute pose and I didn't think it would be worth it to use a piece of my prepared paper so I found a pastel that wasn't working and began to transform it into a new person, a new pose, new light.  In the past I have wiped the old image away and have been left with a muddy background.  This time I simply began working on top. I did that all morning and these were the most successful products.   I like the feeling of time and the richness of the layering.
