I absolutely ADORE this book. I'm a 16 year old art student, and when I'm sketching human form and musculature, this is the go-to book. The models that are chosen are perfect because they're not bulky, they look like normal humans, and you can see some muscle through the skin. The images are side by side views of the photos of the model and the anatomical drawing, which is perfect for trying to understand how to draw the shape and build of people. Especially for in a high school classroom or personal use as a student, it is a GREAT resource. I love it and use it at least once a week when I'm taking a break from larger projects.The only issue I'd say I have with this book is the amount of text and blank space, because I use it to sketch.
