That 15mm Syracusan force looks stunning -- really like the different colors on the hoplite shields, and those celts are gorgeous. What's your recipe for the NMM chainmail armor on them?
I've never considered a 15mm project before, until I saw your minis. The March to Hell prints are a bit chunky and big-headed in 28mm, but between the quality of your paintjob and the 15mm scale, they look amazing.
