"We're all stories, in the end. Just make it a good one, eh?" The Avengers, Doctor Who, Sherlock, Supernatural, Harry Potter, Star Wars, Les Miserables, Disney, Star Trek, Game of Thrones, The Fault in Our Stars, and The Lord of the Rings.
I'm pretty sure the only fandoms I'm not in is Game of Thrones, Pokemon, The It Crowd. Bit I am in Supernatural, Marvel, DC, Cosplay, The Hunger Ges, Star Wars sorta, The Walking Dead, and most of them
I will not hesitate to smack an insufferable 'art' snob up if they EVER disrespect the beauty that is fan art. Art is the act of feelings and ideas being poured out through a more visible medium. The only differing factor in fan art versus original art is the subject matter. Passion = beauty in the art world, and fans have plenty of that.
