Battle Brother Arvemath of the Champions of Athlum, and Battle Brother Haystan of the White Hawks:

And just to show off my nephew's freakin' awesome gunslinger a little more, here's Arvemath standing next to Brother Dagor, selected for this picture by virtue of being the closest:
One thing I can't capture properly on the picture is the eyes - they're Stormhost Silver with the Soulstone Blue (or whatever the blue gemstone paint is) over the top, and they look MAGNIFICENT - even from tabletop distance you can see them gleaming slightly.
