Well, this is my first wallpaper here... I just read about vectoring a few weeks ago, so I have given it a shot in this wallpaper... I have vectored the Shinigami from a screenshot from one of the opening scenes of the anime and for the background I created a scene similar to where Shinigami-sama often is standing...

Ty for the comments. I have reduced the blur on the windows, fixed some points on the vector, redone the clouds and crosses without losing much of the previous shape. I tried adding a new cloud, but it didn't look better with it.
