The Language of Drawing by Sherrie McGraw
So many books talk about painting, but so few really focus on the art of drawing. This is one of my favorites, especially as it has so many beautiful examples to gaze at and if you are ambitious, copy.
Another aspect of this book that I love is all the thoughtful text that supports Sherrie McGraw's ideas about representational art. She presents her ideas so well, and every time I open this book and begin reading a section, I come away wiser and energized to apply what I have just learned.
