When I got my first fanart it was just a sweet and simple sketch, but I squealed happily. I really loved it and was such a great feeling to understand that people just love my characters!
Time passes, things change. I don't get a fanart every day, but there are usually 1-2 pieces per month. Mostly I keep squealing happily, because they're so cute and adorable and people really do their best to make me happy. And I always make sure to thank the person as sincere as possible, repost his/her work to my public and show it off on Tapas/Webtoons
But I started to notice a bit disappointing thing. The more popular I become, the higher is the possibility that people draw fanarts not to show their love but just to get a free repost, show off and gain new subscribers. Such fanarts are easy to notice, because the artists don't care if they know anything about the characters or the story. They can draw for example an aggressive loner as a joyful person, acting friendly to the artist's own character. I don't mind crossovers, but I don't like when the character is completely out of his personality. I also once got very lusty fanart. I don't actually mind NSFW fanarts, but I couldn't take it that my sweet and shy boy acted like a horny slut which is absolutely not him
I always feel very uncomfortable about such fanarts. The reason is that I have to react and have to thank the author, but I don't want to, because I don't like that my beloved character was shown like something he/she has never been.
But all in all I usually cry silently, die inside, say "thank you" and do the repost, because I don't want to be an ungrateful person XD
