If you want to develop your own style, a good approach is to select a painting process and a type of motive, and concentrate of those. This book contains valuable suggestions as to how you can select an approach and a process to painting using floating paint, examplified eith watercolors. The description on the use of big shapes and how to develop them is extraordinary useful. This is clearly an important book for painters with a desire to develop style and process.
I would recommend to read a bit if you havenot got much idea about painting, the book offers some good points as for the painting is concerned, not much of watercolor specifically indeed.
