Here's a cute art site with a rather large FF6 gallery. I only wish I could read Japanese because most of the pieces are accompanied by a description. Scroll down the menu on the left side.
Reader and fellow DA artist theApocrypha just finished part 8 of a very funny and well done comic titled "Locke is a Dick". Check it out even if you disagree. She has other galleries with VI fanart, too.
Finally, my fiance found this one on Youtube. Its a really well executed rendition of "The Decisive Battle" in Mario Paint. We were both sad to see that this video has gotten so few views. This stuff ain't easy to do, I tell you that. So go ahead and give it a listen.
