Sure, something like Nicolaides' "The Natural Way to Draw," is "better," in the sense that it's far more complete. If a beginner were to get through all of Nicolaides' book, and do all of the exercises, that beginner would likely be much better off than he would have been had he chosen to work through Edwards' book. But getting through Nicolaides' book takes so much time and effort that very few absolute beginners will get to that point. They may, however, work through all of Edwards' book. Because after a few days or a couple of weeks of working with Edwards' book, they will be drawing recognizable pictures.
