If you're looking for a step by step guide to drawing, including lighting and composition ... etc. this isn't likely to be the book for you.
If, on the other hand, you are comfortable with not knowing and embracing imagination/memory then you're likely to find these prompts intriguing. I can understand why some reviews claim that this book is a "rip off", it is an empty space with words like .. a burrito ... a skateboard ... a mirage etc. So for someone who needs to be told what to do/how to do it, this causes understandable anxiety. The thing that I like about this book is that it challenges our sense that we know the world, so that when confronted with words like - an antelope, or - bricks, we are forced to think A) What they look like and B) what sorts of marks would be most appropriate in trying to create an image of an antelope. If approached as an imaginative project then, despite my serious review, I'm certain hours of fun will ensue.
