Before I did this pastel, I did a small oil study. In his book Fill Your Oil Paintings with Light and Color, Kevin Macpherson offers a three month challenge: paint a small 6x8 painting every day for three months. He guarantees that one will learn something about painting in those three months. I will attempt the challenge starting today. In any case the small oil seems to have helped with the pastel.
If you are wondering about all these books I refer to: I get them through inter-library loan. I can't afford to buy them all.
