To be fair, that picture is from a moment in the episode where she had reasons to try to hide the fact of being an elf, and used her hair to do so.
(Not that I'm a huge fanboi, I have my own criticisms, but I don't consider that to be one of them if you know the context of covering her ears. If anything I'd rather say it's just a poor choice of source material to make a poster.)
Agree, that picture could be from GoT, The Witcher or HoD or any other generic fantasy/17th century costume drama. For me, it reinforces the argument (in my head) that the show does not feel or look like Middle Earth.
