I would call the book rather than a source of inspiration, since many very good pictures are displayed (mostly caused by Wizards of the Coast, and one or the other might therefore are also known).
Who would therefore still be called beginner when it comes to Fantasy drawing, which is not helped much in this book except for some inspiration, because the way to the finished product is missing. However, if you search only for a few new ideas in this book will certainly find it, because there are many images to archetypes, different scenes represented and sometimes landscapes.
