This was one of the first books I bought when I just started acrylic painting.
This book introduces the reader to different brushes, textures, effects,etc.
I actually did many of the exercises from this book and they came out pretty good. I enjoyed doing the exercises because a lot of the exercises were easy and precision wasn't really required, which let me just work on the basics of things (shadows,etc.)
I definately wouldn't call this a complete course, but it might be a complete course of the basics of acrylic painting (to get you started). I would recommend this book if you're just starting acrylic painting and want a book that's fairly easy to do the exercises for.
