Query: A beautiful presentation, but

It wasn't much help beyond some technicalities of brush work and some reproductions of the artist's work. Okay for a pretty intro. and some history. If your goal is to reproduce someone else's paintings, this book does that; but I want to create my own so Chinese Brush Painting: A Beginner's Guide by Pauline Cherrett, actually gives directions: on how to care for your tools, how to compose your own paintings, how to make your paintings vibrant with energy and spirit, with enough "what not to do's" to be truly a useful beginners guide. I don't understand the 5 star ratings on this book. As to technical brush work; Chinese Calligraphy Made Easy: A Structured Course In Creating Beautiful Brush Lettering by Rebecca Yue; gives wonderful step by step directions for brush work that transfers to painting everything else.
