Inspired by Ian Pain's work (as seen on the DBA Facebook group), I recently completed a European Bronze Age army (Book I/14b) in 15mm using Copplestone Casting's fantasy barbarian range. I went for a bit of a fantasy take on it rather than toning it down for DBA - woad face and body paint and big bronze axes and swords, and hints of Lord of the Rings in the shield designs.
The army itself has a Light Chariot or Blade general, a cavalry or blade element, a couple of other blades, two psiloi, and the rest auxilia.
