I am very thankful for the quality and amount of education in drawing that your book provides. This is something that I will study everyday and will be valuable to me for the years to come. Often these books give a simplistic "just do this" tonality and show a professionally finished piece of art without properly instructing or conveying as to how to achieve that product. My days of frustration are over as your book does the complete opposite of that; it is filled with the generosity of telling me how to achieve these techniques in a very comprehensive and easy to understand way.
