Tentatively, SuperJoshua.com. Primarily, my working through the book, The Natural Way to Draw, by Kimon Nicolaïdes.
Four tacks, this time. Kimon suggested that I should redo this schedule. I agree, it probably would be helpful. And I probably will redo it--when I start the book over, again. For now, I press forward, not because I have mastered anything, yet, but simply because I know that if I stay here too long, I'll stagnate here.
