Well, it doesn't really bother me too much as it's just fanart, and fanart doesn't always represent canon. So no, I don't think this type of fanart "ruins" her character; it's just what another artist wanted to depict her as based on his opinions of the character, and it has no effect on the character in the show.
If it really bugs you, my only suggestion would be to just try and ignore it, and remember that fanart and the source material are two very different things, and a few pieces of artwork that depict a character in a certain way rarely ever leave a huge impact on said character.
