The Tonal bar Exercise. I find this exercise good on focusing on my tonal transition skill, that is the very gradual transition from dark to light areas. used for achieving that 3D form, the soft edges as they call it, the illusion of mass.
Few more exercises from this book and soon I’d be looking up to taking lessons from another book. Advance thanks to this really great drawing lessons book. I learned so much, not just how the strokes are made but the book very well managed to teach how professional artists think, perceive and approach the art of drawing.
