I bought the Warlord Games ones from eBay a while ago, they had quite a thick layer of Army Painter on them. I managed to turn this to an advantage and make the 'gunked' hair into turbans. As the AP had taken away of the hair detail, they could be painted white and become very effective turbans. Thus giving these Greek Slingers a more Eastern look.
I didn't give the unit a standard or musician, but instead gave the commander a shielded bodyguard to make him stand from the rest. It instantly made him look more important than the others.
