Love the fanart. Since forum notifications are failing you might want to contact said authors by discord or tag them in social media. This thread works as well. I am only mentioning those options in case you hadn't thought about it.
If you don't have their discord or social media I think it is time that authors who like each other start sharing such important info so that they can mantain a close contact with each other.
P.S. I'll send Lyn a message to check out forums and see the fan art you made in case Lyn hasn't checked forums. Would be a shame to miss such a great work of art.
