Personally I dislike backgrounds where the focus is in the center, because it's obscured by the main content. That's why my backgrounds always have the plants to one side and the zombies to the other. Regardless, we certainly can use official artwork as the backgrounds if it comes up. As for the size, that won't actually matter too much since the background has to be low quality anyways, under 300 KB. It might still be a little more blurry than others, but it won't be too bad.
