After reading the book, and deciding to make a go at it myself again, I can say that the advice given in this book is great for anyone that has a little working knowledge of some sort of art/ painting. I wouldn't recommend an complete novice to dive in to this. Of course, you will learn some great techniques, but for a novice painter, you really need to start with the basics.
Even though I haven't painted in ages, I was able to pick up the techniques outlined in this book. STILL extremely sketchy on doing portraits, but I'm willing to work at it! You won't get any better at it if you don't practice!
The only thing that I was kind of bummed about was that it focused a LOT on portraits. I would have liked to see more, or an even balance of all the subjects listed in the books. The landscape painting section got the least amount of attention. Overall, still a good reference book.
