Great news! I contacted support and Tom Fulp himself responded and re-published my art! I'm very happy that it was fixed so quickly. I think I might be in the clear as I pretty much only work with content that I have put my own sweat into--but I realize a lot of my colleagues might be out of luck.
While I've stated it many times in the past, I do give full permission for people to pose/animate my released models on any website including Newgrounds.
