Query: I enjoyed it. :B

I started reading this book from a paperback at my local library and I enjoyed it enough to buy it on my kindle. Although if you're really trying to improve you're artwork I suggest you get the "Drawing on the Right Side of the Brain Workbook" as it focuses directly on the excersises and less on science and psychology. Which is interesting but examined overly in detail in the main book and may bore some. Also, one of the first excersises calls for a bit of tracing which doesn't work on kindle, whoops!
