Thank you very much for the video, launched now, it must be a fantastic book, very interesting, thanks.
i agree with what you say, Tonal contributes to the magic of drawing, of art, a magic in magic.
Shaging personally I find it one of the toughest things, however I really like how you're doing.
Ps: I really like the first charcoal in post # 80 and the hand is fantastic.
I find these drawings fantastic you posted, portraits with hatching are a beautiful show (perfetti ), like the drawings of the hands, you are posting wonderful posts. Great job.
