To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is a good start to the background of Sumi-e Painting. It is well structured and the examples are clear and easy to to follow. The illustrations are large and clear. The beginning also helps a beginner to know what to buy to get started.
Had to buy another book by an actual master in sumi-e to learn correct techniques after buying this book. Most of this is pictures without telling you how to do it. Lots of paintings in colour and with multiple lines and layers which is not sumi-e but rather another form. More of a portfolio book and not at all a lesson book.
