This book is excellent as it goes step by step in the process of character creation working from a sketch and creating a fully rigged, animated and textured model. It covers the new cutting edge features of Blender when it comes to mesh creation, sculpting, and retopology. This is the first book that I have read that was able to explain in detail the different techniques that can be used in Blender to apply re-topology to meshes. It covers each topic in detail and allows for the application of several techniques to accomplish tasks. While this book seems geared towards an intermediate level of blender experience, a beginner should be able to easily pick up the topics in this book and be able to learn complicated processes is very little time.
