Understanding the architecture of skull and musculature of the head is critical to furthering your skills of portrait drawing and expression. This 2 disk CD-rom Atlas of Facial Anatomy presents the skull and musculature of both the frontal and 7/8s profile views giving you a 3-dimensional understanding. Unlike anatomy books which present you with a bewildering array of terms, this CD-rom atlas begins by building up the skull step-by-step and then proceeds with the deepest muscle layers and builds up the forms and structures of the human head muscle by muscle.
