The format and content of this book are spot on. There is so much content it will take quite some time to get through the book if you really look at it, as any artist/sketcher (as I am) will be interested in the Artist profiles and how they produce their work. It's an eye opener too regarding the variety of styles employed - so many differing ways for each individual to capture what is in front of them. It makes you want to pick up your own sketchbook and get out there and do more of your own . Artist's and non Artist's will enjoy the wonderful variety of work on show within the books pages. Recommended.
