I was looking for a tutorial with enough detail to allow students to shape and position tone muscles. It has good qualities. The skull is slightly more detailed than the appendix bones - the skull has a removable skullcap with a visible Turkish saddle, well-done main seams, and so on. Large appendicular features such as trochanters are visible, but do not expect comparable small details such as tubercles to appear on appendicular bones. Overall, it's very well made and far exceeded my expectations for the price.
