Analysys of armor (I hope there's a full set)
By looking at this soldier, she might be a militia soldier. She only has a regular helmet and doesn't even wear lamellar, which is the standard armor(i tired to make a felt one to replicate leather models).
I cant find any examples of this helmet, but this should take place in the Early Qin Dynasty, SInce the great wall is built. Also civilian clothes are accurate 10/10.
