Lots of blah to say nothing and very little concrete exercise .. Really disappointed with my investment .. He has not learned how to draw drawing explain .. but .. I wished NUANCE learns this book and my ma-times nothing learned new, yet I am beginner .. The quality of the drawings in this book are the means, it goes further as it is for dummies but what I can not forgive is the number of works in this book which is minimal and repetitive and lack of exercise .. A avoided if you wish to move fast!
