The drawings are very thin, for some it takes a good eye and patience. I am less a fan of his reasons for which some have seemed daunting, or even double. I preferred the Mini-coloring "India" where drawings are prettier and less boring.
The fact that the pages are detachable is very convenient but after a while you end up with a pile of leaves that are sailing in the hardcover book (° _0) and I agree that bothers me a bit here.
Cà's still a good time to relax for a reasonable price.
