Thank you for producing this wonderful workshop on Symphonic Composition and Portrait Drawing. You have provided a great wealth of information in both workshops.
Having a technical background in electrical engineering, I have to admit that I was particularly lured by the information in your first workshop on symphonic composition. In my opinion, though it might be technically biased, it is your workshop on symphonic composition wherein you provide the true "Masters Key".
I like to think that I have done extensive reading on art instruction in an attempt to self-educate myself, and I have to say, that you have provided a comprehensive treatise on composition and design that is difficult or nearly impossible to find elsewhere today.
In fact, I have to confess that I was quite perturbed by how little I knew about the significance of Phi with a master's degree in engineering. It took your course on Symphonic composition to propel me to explore " Sacred Geometry" ! I was consumed with the subject last winter when I suddenly realized that I was quickly drifting back into technical doldrums of mathematics far removed from my art.
I really have yet to come across a book that provides as comprehensive a course on design. In this workshop, you clearly elucidate the placement of the center of interest in relation to the entire composition which of course is crucial. I found this course extremely stimulating.
