Thank you very much for the opportunity to learn from you! In my opinion it was very informative! When I was studying PMU (2 months ago), I did not learn shading at all! I continue to train on and on paper, and on latex and on the models - I really see the result! And the book is also amazing. All is in essence and what the master needs to know! (After school, I read a few books, but they was not useful). P.S. Elena has very beautiful works! Thank you!
