Hello, I'm new here!
I wanted to add some more information about Persians nation.
The face of king Cyrus II is somehow Arab lied face,
I sent a picture of a more Persian liked face structure. Furthermore, The Immortals appearance isn't like the original Immortals. ( I uploaded their picture too )
Also, Persians did not Farvahar ( the one with a ring in his hand ) sign on their shields because it was a religious sign for them. Some of them used "Derafsh Kaviani" as their flag on their shields.
Also Most of Ancient Persian soldiers used Some sort of helmets which was called "Khud".
You can take a look to the pictures for more information.
