The X to be the same size as other icons.
Linkedin to be black and white like the others.

PS: Maybe now would also be a good time to consider pulling those links from wikidata since it is a great source and currently doesn't seem to be pulled from there. Pretty much all wikipedia pages have wikidata pages with rich social links.
