Minor thing I want to praise: I like the paneling for the two pages where Light cuts off Naano's hand. Going from one panel where he forces the knife out, then reusing the knife as it falls to the next panel where he grabs it, and finally showing off the conclusion on the next page.
Not gonna say it's anything groundbreaking or that the idea itself is executed the best it could've been, but it's just a small thing I liked.
