I recently have been doing ton's of figure drawing to hone my craft. When i get to the point that i want i plan on just kicking out tons of work. The art books right now that i have found especially insightful about Human anatomy are: Anatomy a complete guide for artists by Joseph Sheppard, Drawing Lessons From The Great Mastersby Robert Beverly Hale, and for use of color and light, Color and Light by James Gurney. I would recommend them all. They have been very helpful, and a must for anyone who is serious about painting or artistic anatomy.
