Painting book on heads and faces

I have been reading a book called

Painting Heads and Faces (First Step Series) by Pat Clarke that I got at the library.

It is a very good book for learning how to paint portrait style faces because it starts out with a basic tutorial on how to draw a face properly, then shows shading and how to make the drawing look the same as the picture you are working from. After that are detailed sections on painting each feature properly followed by tutorials that go start to finish through painting subjects.

I've decided that I am going to add this book to my painting books collection so I can keep it handy for referance use. (As in buy me a copy, not steal from the library, sheeeesh!)
