We have not used this particular book, but we have subscribed to the artist’s monthly e-newsletter. In the fall of 2012, my youngest dd12 had the opportunity to attend one of his 3-day art workshops, and it was affordable (Mr. Stebbing allowed us a huge discount) and very helpful to her. She has never had formal art lessons but loves to draw and create things.
If you see on his website (linked by the OP) that he is coming to your area, I’d recommend attending his workshop.
