From the computer to the tabletop, this is all about games. Updated each week-end.
I took a similar but different painting route when completing the Hearthguard. Like the warriors, I gave them a ghostly paint over. However with these models I armed them with swords rather than spears, and used a glowy effect similar to the one I did on Aekold Helbrass.
Using black rather than blue gave me a contrast between the ghosts and their weapons.
Method and paints:
The bodies were simply painted with Black Templar over a white undercoat and then drybrushed with white
Next, the swords received their glowy treatment
Finally the bases were painted using the Mystic Sands recipe from Xenus Minis.
