really? the guy who reviews art books doesn't know how many art books are out there with identical foundamentals and teaching methods cause there is only one simple way to do it? even my watercolor books have the exact same naming system, layout,and tools. now we can't use the words like " value" and " line weight" cause he thinks he invented those? how can you buy into this, he is doing it to boost his own sales
if this is gonna get legal ,the guy is looking for a defamation lawsuit
