If you submit this as Customization/Wallpaper/Vector does that indicate the style or could it also indicate the file type? I think if it is vector graphics, you should release the vector file too, so that people can upscale the image to their monitor resolution if needed.
If you want to know how to render different sizes, let me know. I haven't used Inkscape in a while, or any of the other Linux vector editors, but it should be simple.
