Just to let you know Larry, I did read a few pages of this book at Amazon.com. The author seemed to make effective and interesting use of imagery, clearly distinguishing the book from those in the "pulp fiction" category.
Surely it must be better than the "Drawing with the right side of the brain". I admit I only got about 100 pages into that one before I found a replacement ("Lifelike Drawing with Lee Hammond"). It has its own methodology too. It is very "gride based" with a lot of emphasis on how to produce realistic shading (but I didn't realize that when I bought it). I guess you take a little from here, and a little from there, and you do what you do. Yes, you can quote me on that... :)
