I thought I'd saved it in Pictures>Banners>Made by me>Vocaloid, but instead I'd saved it in plain old Pictures>Banners>Made by me>xcf, and that folder has so much crap in it it's not funny. There's so many unfinished banners in there, and banners I never bothered uploading to my photobucket. I found it now, though. I'll finish it this morning and upload it.
