I am an illustrator and thought this book would help me with the drawing of facial exprssion, especially with children.
Unfortunately, I am disapointed that too many of the expressions photographed in the book are not realistic: the children make faces, they obviously had much fun during the shoot but very few of the photos are usueful at all. I was hoping for more photos of faces expressing actual human emotions, not open mouth and grimacing faces. The book seem better for people drawing caricatures or possibly cartoons, but not very useful for realistic picture books.
A positive however: the age progression gallery at the end of the book is of interest.
Finally, the book is VERY POORLY MADE and the binding came appart with two days of actually using the book.
