This is a very good book, although a little drawn out at times. I think because the authors passion(and i hate to say this) gets in the way of his teaching throughout the book. He is very excited about what he is saying that sometimes he seems to ramble.
Although, what turns into going on and on about a topic also pleasantly turns into a history lesson, where the author takes you through a variety of drawings from various masters.
It is well worth the money and will inspire you, just be a little prepared for what you are getting into. A thesis about movement and suggestive movement in drawings across the ages.
Actually, i really enjoyed it probably more than 3 stars, but for it's relevance and need to own i felt it deserved 3.(not everyone will enjoy it as much that is for sure.)
