This is book #9 from the Sketching from the Imagination series. It's kinda difficult to keep track of these books because there's a new one almost every year.
This 320-page paperback is thick and is packed with beautiful concept sketches relating to magic and myth. Over 50 artists over the world have contributed their art so there's a good variety of styles to see. Each artist comes with a short profile and provides some drawing tips.
I've already featured so many of the books from this series that I'm not sure what else I can say that I've not said. If you love sketchbooks, these are the books to get. By the way, 3Dtotal is offering good discounts for bulk purchases.
