I bought this art book along with the others (there's a total of four in the series) because i'm a big fan on Kantoku. When these arrived, it had exceeded my expectation. While each page was just a rough picture or line art, you can still make out how the picture is. And the another thing about this is that on each page, there's a bit of it is coloured in the same colour as the cover, in this case, is blue, which I find awesome!
