When I saw this scan, I realised that there are few wallpapers out there with it, mostly in low quality. But I liked it very much. So I decided to wall it by myself. The trees are 3D, the grass is real (shopped) and the sky is very shopped and not originally belonging to the grass. I benefited from the fact that Dejiko looks as if she was cold - hence the autumn theme. I also added the waist, because this scan, as apparent in the Scans section, doesn't include it.
I have used the resolution of 1600x1200 to give you the best possible quality.
