I made a Terezi background for one of my great friends. It comes in BLAPCK and white, with special edition CH3RRY R3D (warning: CH3RRY R3D is pretty blinding. Use with caution).
IMPORTANT NOTE: THE TEREZI IN THE BOTTOM RIGHT IS NOT MY OWN WORK. I FOUND IT ON SKAIA.NET BUT THERE WASN’T A SOURCE. IF YOU MADE IT PLEASE TELL ME.
