I really like these!
My one suggestion, if you wanted to to pull them even more into the 'historical fantasy' astethic, is to start doing some mix-match armor styles, such as putting on helmets inspired non traditional helmet types - thracian/phrygian types are one of my favorites, and to do some things with scale armor. Scale armor, to me, has a certain 'timelessness' that lends itself better to fantasy. Lorica segmentata is SO decidedly Imperial Roman I feel it's almost too on the nose.
But the quality on the minis as it, is wonderful!
