This book is for children but it would also suit any adult who's interested in learning how to draw faces. It's a 60-page book that covers quite a lot of broad areas including all the basic technical aspects of face drawing as well as how to deal with angles & lighting. There's also a range of drawing styles you can try out - everything from fine art to modern & quirky to cartoon to abstract!
Because it's primarly been designed for children, the book is written & illustrated in a way that is colourful, fun & accessible. I've got a few other drawing books (for adults) and none of them are as fun as this one or got me drawing as quickly as this did!
