Over several years of creating art, there are a few books I have found the most helpful, inspiring and informative for the kind of art I do, and now, having teamed up with The Bookshop, an independent book store in East Grinstead (at which I happen to work!), I can offer them to you too!
You Will Be Able to Draw Faces by the End of this Book by Jake Spicer
I struggle with faces. As Grayson Perry said 'I am not one of life's natural portraitists'. However, this book breaks down everything you need to know simply and quickly. As a succinct review: you really will be able to draw faces by the end of the book.
This may not be the cheapest you can find this book, but every sale benefits indpenedent store The Bookshop in East Grinstead, a wonderful, beautiful, historical, haphazard place of books and coffee and cakes.
