Nice details and looking good. By the size of the units and force, I am guessing SAGA.
A small nit-to-pick. During the Samnite wars and even the Pyrrhic invasion, the Roman soldiers had to provide their own gear and uniformity was not common at all. They pretty much wore what they wanted. It wasn't until later in the Republic that the state took over equipping soldiers where you start to get the "uniform" look.
That being said..... who cares! I think they look great together!
