I did this wall after finishing that Ichigo vector (can be found here: http://www.animepaper.net/gallery/scans/metzalx/item259458/)

It's a fairly simple wallpaper, I originally had a black background with Ichigo emitting blue reiatsu, but decided that the parchment background made more sense (it helps a lot that his hair is orange).
