Surprise these aren't on the list, since they're the larger communities that post fanart on DA o.o

http://marblebridge.deviantart.com/ - A group I made on DA some time ago, It actually does have a decent collection of XIV fanart just scattered ( I should reorganize it better someday ( Q w Q ) I haven't maintained it very well past 2 years but people do still often post fanarts of both XI and XIV.

http://the-gobbiebag.deviantart.com/gallery/ - another XI/XIV group on DA, not as many members and doesn't get as many posts as the MB though.
