I don’t have any Warlord to compare to at the moment, but Steve, of Age of Glory Historical Miniatures, the U.S. distributor of Empress Miniatures, was kind enough to send me a couple of sample figures to compare with my Rubicon figures.
They are very nice, clean figures, but as you can see from the photo (Empress on the left, Rubicon on the right), the Empress figs are a bit larger in proportions when compared to the Rubicon, but they are still far less “heroic” then Warlord figures.
