to my knowledge IS is quite strict on that in the past I got some statue images rejected there  having said that  you could see many approved statues there as well. other than that it should  get approved on other sites imo. but I can't really give legal advice on if it's smart to sell image of statues with RF license. but  I don't shoot statues anymore even if I did I ,I try to sell them  as editorial  licensed  rather than RF  to be on the safe side.
