Those are terrific! I would love to have a Dacian army some day. I've gone for a little later with mid-Romans and Sassanids. I think there were still some Dacians around, but my first next opponent I would love to have would be Goths. Not sure what to do about figures for those - I'm not that keen on the footsore infantry but the Footsore cavalry is first rate.
How do you find painting patterns? I've just started working on some Gauls and I had been put off for a long time worrying about the patterns but I'm not finding them that problematic in reality. Of course it's a little more work than a solid tunic or trousers, but the only real challenge is figuring out which color combinations work well and are believable.
