I am a generalist artist and I love making characters from universes I love (movies, series, games ...) I use the term fan art to make it clear that it is my vision, my reproduction of an existing character and not a likeness with all the identical characteristics. That is, I am not selling the original character, but my view of that character. The company has every right to find it wrong since they own the rights and may have it removed from the site and I will have no choice but to remove it. But I believe that the vast majority are not concerned with the guy who does some random things. The public that buys an original reproduction of a collectible paying thousands of dollars is not the same as who comes here. Another important point is that "fan art" allows you to get to know my work and may be interested in making proposals for me to develop something personal. If I created a personal orc, for example, I would draw less attention
(I even saw your photo and just created my Azog lol)
