This is concept art for Valerian infantry from my ancient fantasy world. The Valerians are the setting’s equivalent to ancient Rome, characterized by a volatile republican government and a cultural disposition toward militaristic expansionism.
When designing these soldiers, I ran into the issue of balancing the Roman vibes I wanted them to give off and the need to make them their own civilization rather than just transplanting the real historical Romans into my world. One change I did make was in their helmets, which have influences from those of Spanish conquistadors and medieval Italian crossbowmen alongside the obvious Roman ones.
