Nicolai Blokhin Drawing Demo Videos
Nicolai Blokhin is a contemporary Russian painter. His work is classical and clearly influenced by Russian masters such as Ilya Repin and Nicolai Fechin.
I have have been particularly impressed with some of the preparatory drawings for his paintings because of their qualities of character and robust but simple sense of form. You can find these drawings and lots of other very impressive work at: http://www.nikolai-blokhin.com/index.php
(And some of these preparatory drawings are shown in the background of video 2 below, which gives a sense of scale.)
Below are links to a few YouTube videos of Blokhin doing public drawing demos which I found very interesting.
