So far, everything I have read has indicated that I'm on the right track (a good feeling), or has answered a nagging question that has never been answered for me. The list of oil color pigments in the back is worth the price of the book. I'm not even half way through and the good stuff is still to come!
The frustrating thing, of course, is that I wish I could have read this five years ago. Any serious young artist out there should snatch this up quick. Buy it here.
