Incredible miniatures, love the way you painted them.
Do you do an overall sepia/brown light wash to get that faded and unified look, or is it just the colors that you're using? I really like how, even if they're all different, they feel like part of the same army due to the cohesive paint job.
Also Antiochus does look a little on the big side, but I think he blends in really well with the Aventine figures. I also have the Aventine later hetairoi and was considering buying that same Antiochus, will surely do it now that I've seen a side by side comparison.
