This is the sequel to the first volume 速写时光 (Sketching Times).
They have increased the number of artists featured to 30, and pages to 336.
The content feature still focuses on character designs, with the occasional mechas and creatures. They are mainly from Chinese artists. I don't know any of them but all their sketches are fantastic. There's a touch of Asian style to the drawings as compared to Western style.
As for the quality of the physical book, it's still paperback with that recycled paper-like brown cover. The paper's the off white slight yellow kind which will probably turn yellow after years. Not too bad really considering the book is around US$20. I bought mine at Basheer Graphic Books again. You have to ask them for shipping charges, and they communicate in English.
It's an inspiring book. For the price, it's really quite worth the money so I'll suggest getting both volume 1 and 2. This book also comes with a blank sketchbook, with the same paper quality.
You can order the book at Basheer Graphic Books.
