''Kanji'' Book

I made this book for a friend who learns japanese and wanted it to practise kanji. The front is obviously inspired by the japanese flag and on the back I tried to recreate my signature in the style of a kanji.
Being finnished only one day after being asked for a book, this 11cm x 16cm, 256 pages (counting both sides) book is the fastest I made, and I'm quite pleased with its look and quality of crafting. Yet I'm still not happy with the photos I take.

Please feel encouraged to tell me what you think!
