I think this method was designed for people who tend to draw the conceptualized images, especially for the parts of human anatomy, that are held in some people's brains - rather than what is actually in front of their eyes? So, basically, it is a way of tricking the part of the mind that can get in the way when people who claim that they 'can't draw to save their lives' - especially when it comes to people and non-human animals.
In short, this is most definitely not a book for accomplished artists, like yourself. I think it was intended for people who would love to be able to draw and paint but who think, mistakenly, that they don't even have it in themselves... In other words, it's just a stepping stone to help them gain enough confidence in themselves to even get started in the first place.
Once they have finally plucked up the courage and got over that initial hurdle of thinking that they simply can't do it, then of course, they can start working on practicing and 'improving' their art, if photo realism is what they are aiming for. (For that, personally, I prefer to use a camera)!
But they have to get started in the first place - and that is what Drawing on the Right Side of the Brain really helped me with. I can honestly say that I wouldn't have had many a pleasurable hour with my drawing and pastels without it. I would have been dreaming to this day.
So, the main point of the book is that it is a mistake to think that people can be divided into those who can draw and paint and those who can't. Anyone can. Some people think they can't - and this book is for them, not you!
Thanks for your feedback on this article, anyway. This is always most welcome!
