I think that is the problem - learning what you see is flawed and shouldn't be the first step. If you look at Vilppu's drawing manual, or take the Fundamentals of Drawing class at Watts Atelier, and countless credible university courses, what you'll find is opposite of "learning what you see". I can understand that drawing a cube, cone, cylinder is very boring but so is learning chords or music theory in practicing Guitar. That said, if one doesn't want to take drawing seriously and just want to have fun (See conflicting Amazon reviews on Betty's book), Betty's book perhaps is entertaining. I just have a problem with its popularity and will probably lead people into delusion that somehow they have managed to conquer the drawing. Drawing is hard. I also lose respect for authors that despite of knowing nothing about the field or making any attempts to study/understand, they have the audacity to publish their own version of "how the brain works". It bothers me.
