This wallpaper comes from a screencap of the ending theme to Sayonara Zetsubou Sensei. Ever since I saw it, I’ve been eager to wall it. I vectored the screencap to get rid of the credits, although the trees took a lot longer than I had hoped. xD I also added a bit of detail to the knife (the handle was originally just brown) to match the close-up shot of the knife that appears in the previous frame. Since the animation for this series is delightfully unique, I decided not to change or add anything else to the original image.

The original screencap: Sayonara shot

It’s a straightforward wall, but I thought it was representative of the mood of the series.
Are you in despair? ;)
