I have played a little bit with the artwork for the upcoming release for openSUSE and noticed that the XFCE splash screen is using older version of the artwork than the rest of 12.1 so I prepared a replacement (attached). I got in touch with the XFCE team and they seem to like it and Guido Berhoerster asked if I could contact you guys and get the image and the svg source checked into the art repo.
I have cloned the art repo and prepared a merge request with the two files added.
Let me know if you need any more info.
