Before Christmas I bought Bert Dodson's book Keys to Drawing with Imagination. The first few exercises focus on doodles, or rather doing more with doodles. These are some of my examples from the first exercise. I like this book. Even the little doodles feel inspirational. While the book feels like it would be more useful for illustrators, I'm getting a lot of out it. I doodle as much as the next person, but some of these doodles are new to me. As I read through the exercises, I can see how many of these could evolve into paintings. I'm enjoying working through this book.
You won't find much in the way of actual drawing technique. The book does have a lot of good tips scattered in it. There are instructions for building your own light box. There are also many tips for combining and transforming your doodles and sketches into new drawings. The last part of the book focuses on artists and some of the themes they've chosen for their work. I think I'm going to get a lot out of this book.
