Pretty cool
The animation for the Note, and the transition between pages was well made, with only some sketchy parts on the page lines and blurred names(though I can't remember if the Death Note actually has lined pages...).
The information had some mistakes, but it was overall correct. Though you could've put a lot more for L, and also added minor yet also important characters like Watari and the others that "fought" against Kira in the first part of the story.
The music and the addtion of the "How to use it" page are great pluses.
