To add to this on Tomyris, the Massagetae were from modern-day Turkmenistan. The Ossetians are the closest linguistically to the Scythians because they speak an Eastern Iranian language (like Avesta), but there's no reason to assume they're closer genetically than Eastern Iranians. There's a lot of genetic mixture and Ossetians are no exception. So Tomyris is probably fine. Lebanon (an ancient name) has people who range from pretty fair or fairly dark. Civ V Dido is fine, but so would someone who looks more like how Tamar is depicted. Tamar is very dark for a Georgian. There are some depictions where she looks like that, but they're the minority. Cleopatra looks Greek. I don't know if I'd go as far as to say Pedro II was blond (not blonde), but they should have looked at more than one picture.
