DO NOT USE THIS BOOK TO LEARN.
Listen, I love this book, I've practiced with it for almost a decade, I love the artstyle, the tone, everything but....hear me out...
THESE DRAWINGS HAVE ZERO CONSTRUCTION.
I know this because I actually took the time to lay a grid on top of them, and realized there is no consistency, no symetry, no construction, no nothing. And yet, somehow, they work. They are beautiful, stylish and alluring. But they are neither anatomically correct nor balanced.
If you want to learn to draw, do not use this as a text book. Use it as inspiration, but for actual learning, you are better off using the Loomis Method or Preston Blair's Advance Animation. Trust me. DO NOT MAKE THE SAME MISTAKE I DID: I spent six years trying to replicate her artsyle, blaming my failure to do so on my lack of talent when in reality, I HAD TOO MUCH TALENT, that's why I couldn't copy something so unbalanced and chaotic as her drawings.
