From my experiences, it is considered fan art if no monetary value is earned in any way.
You have to acknowlege that it isn't associated with Nintendo and the Developer of Zelda.
You can not benefit monetarily from it in any way, directly or indirectly.
Money is considered a Contract.
It is illegal if you get any money from it in any way.
If a penny is earned it looses fan art status.
If Nintendo, or the developer of Zelda asks you to remove it, you should then remove it.
If you refuse to, then they will try to find a way to make it an issue.
Facebook may remove it if Nintendo or the developer of Zelda submits a request for removal to them.
If it gets removed, you can make it a different game by changing the art and text.
Just be sure to remove anything related to the issue it was removed for.
I don't want any liability from this reply, so I have to say to recheck with others and/or other websites.
Asking this to somebody more knowledgeable should be done as well.
