In Week 4 artists investigate the hands in-depth. Hands are one of the most difficult parts of the body to sculpt and demand the utmost attention to construction, proportions, form, and gesture to do successfully. They are second only to the face in expressiveness so we spend the entire week doing a single detailed study of the hands in Zbrush. The lessons learned here will be important to transfer to the full-figure sculptures started in week 6. After a lecture covering the anatomy and proportions of the hands, artists sculpt using the best reference available – their own hands. This week also includes lectures on making hands using Zbrush’s flexible and quite useful ZSpheres and reading assignments from George Bridgman and Andrew Loomis.
