In all honesty, i haven't found this book as useful as I'd hoped. Some of the poses are too contrived to be of any good to me ( check out Threading the Needle...wtf )and some of them are inaccurate depictions of people using various weapons, like who holds a sword like that, I wonder ? Also I would have welcomed more in the way of different male models, the three here are all slim, youngish, no muscle definition to speak of, which for me was disappointing as that's what I like to paint the most - muscles ! A couple of the poses were repeated with different models, which I thought was unnecessary tbh. I suspect that to get the most out of the book, you need the disc that goes with it.
But it's a good learning tool, just no good for inclusion in finished art I'm afraid.
