This book is an awesome resource/refernece book for drawing almost any animal you wish to draw. It includes many images of animals in action, which helps as a reference when you don't have the option to see the animal in the flesh. Some images include the native scenery of more exotic creatures. I use it to help an idea in my head come to life on paper, for pen & ink, colored pencil, or printmaking designs. This book is my first source to draw an animal (if the option of a live model is not possible!) The illustrations have more depth and interest than a straight forward encyclopedia of animals, adding to a more creative treatment of subjects. Easily my most often used resource book.
