i tried to capture a bit of the series in the wallpaper. examples: i used a tip of a blade covered in blood to represent death as well as reds/yellows/oranges to represent violence/rage. i also added in more chains to kind of make the other chains in one of the scans i use work together. i tried to make it darker to give it a dark feeling since you it's Death Note i hope you like it.
