Hi! I just found your blog and I really enjoy and appreciate the book reviews you are doing, like these. I'm a bookseller/buyer, and just LOVE books like this - anything to do with pencil sketching - even the most basic instructional book can be such a joy to look through. I haven't seen any yet by Mau-Kun Yin, but now I'm going to keep an eye out for them. Thanks for the wonderful photos!
