Summer sessions of my anatomy and digital sculpting courses have just been announced and are starting in late June. If you are looking for an intensive course to seriously expand your artistic skills, consider one of these:
The most comprehensive online course covering artistic anatomy. No prerequisites are necessary, just a sincere interest in learning about the wonderful machine that is the human body!
An intense ten-week course in the tools and techniques of digital figure sculpture. This course is recommended for students with a firm grounding in anatomy (the Anatomy for Artists course is recommended) as well as an intermediate knowledge of ZBrush.
The companion course to Anatomy for Artists, this course explore the anatomy of the face in-depth. It covers the construction of the skull, features, facial fat, musculature, expressions, and the Facial Action Coding system (FACS). Every great figure needs a great face, this course teaches you the anatomy you need to build it.
