I believe the deadline has long gone and passed, but I can’t help but point people to entries posted on a community I help mod:
https://community.livejournal.com/ffxiljcommunity/tag/fan+art
I haven’t really checked the other communities to see what other players might have done, but if you have something to share please leave a comment or join the FFXI Lj Community (*you must be registered with Livejournal.com in order to join the community and post)!
