Problem Solving for Oil Painters: Recognizing What's Gone Wrong and How to Make It Right

This book suits more for the serious beginners or intermediate painters 'cause you have to be familiar with the basic concepts. It offers a way to verify the quality of your paintings point by point.
My point of view is that you have to read it entirely before you can point on the problem. The topics are easy to reach after you know what you're searching for.
Sometimes I would like to have more examples or explanations on some points.
Simple but effective if you're not a complete beginner...
