@Amirrora: I found the first and the second artwork with google pictures. The first one is some kind of herbalist (another life job) but I don't know if the second one is rly related to LO. But it was suited for the signature.
The third one is from the official website. It was originally a wallpaper.
Edit: ah and the backgrounds are from the official fansite kit.
