i didnt find any vector art, but on the official website they had some wallpaper in a fairly high res format.  
give us the URL. 
I guess it could be traced easily
Here is a rough layout of the side art i've come up with, suggestions are more then welcome  the actual size is something like 22" by 30" and its going on a black laminate cab
nice. 
I find there's to much space betwen characters. 
you can wippe out the black background of your side art, just keep it on characters. 
1) it will produce a smaller image
2) the 2 black colors, black laminated and printed black will be different, this will produce a sort of underlined graphic.
