If I remember, we already had that picture for Arianna's page years ago before the current image. Plus I say the current image is fine the way it is. It's the only good one we have of her from the movie. The one you're choosing looks too sad.
I think you should give it more consideration before making a decision like compare it to the current profile image. I simply think this might be better suited for Queen Arianna whereas I find the current image to not suit her as it makes her look too shocked, but I find this image sees more of her beauty even if it does look slightly sad.
