Some must-have books for sculpting would include "The Complete Sculpture Handbook" by John Plowman, "Sculpture: Principles and Practice" by Louis Slobodkin, and "Modeling the Figure in Clay" by Bruno Lucchesi. As for the different schools of thought, yes, Russian, American, and Italian approaches can vary in technique and emphasis—Russian schools often focus on classical realism, American schools may lean more towards modern interpretations, while Italian schools have a rich tradition in Renaissance techniques. It's definitely worth exploring different traditions to broaden your understanding and find what resonates with your practice! https://www.proko.com/community/topics/my-first-zbrush-bust https://escaperoad.co
