They look great, Panos! I like the changes to the leader, standard bearer, and swordsmen, once you get the dark grey swords, very much!
I have mixed feelings about the infantry helmets. The helmet you originally had on them make them look more like traditional infantry peons. If there were vast quantities of them compared to the more elite swordsmen and guardians, I think the use of this helmet would be fine. If, however, there are the same number as there are guardians and swordsmen, then the new helmet increases their status, yet still puts them beneath the swordsmen, and makes them look a bit more fierce and menacing. I think it really depends on what you're going for.
