Some backgrounds that I've made for several commissioned comics. The second and third one are the pond from "Too Many Pinkie Pies" and some of the outside of Twilight's library respectfully while the top one is a random night scene I made that is supposed to be somewhere around Canterlot. The top one's comic hasn't been released yet but will be soon. If you would like to use them, there are links below but they are rasterized, not vectored, so they aren't of the greatest of quality but they work well enough for smaller images if scaled down in a decent enough program.
