Ok so this is what I did, using Vallejo Game colours and GW Metallics.
Armour and sword - Black, Chainmail, Blue ink over, lightly Mithril silver over. Blue ink in the recesses and Mithril shines up on the plates.
Robes, Faces - A couple of thin coats of Magic Blue. Face and fingers got some Electric Blue on the high points (brow, cheeks, etc). Robes were painted over with Electric Blue, leaving the darker Magic Blue in the deep of folds, leaving a distinct two tone effect.
Chains and ornaments - painted Mithril Silver and blue ink on the gem type ornaments. Just something simple.
The "ghosty" effect - I mixed 1 part Electric Blue, 1 part Wolf Grey, 2 parts Elf Skintone. This made a blue/slightly luminous grey, which I used to sharpen on the edges of the robes and to the flesh. Another mix of 2 parts Wolf Grey, 2 parts Elf Skin tone was applied to the flesh, and lightly drybrushed on the robes. A little Blue ink was used to make eyes and mouth stand out a little.
Painted base wolf grey (Crystal Lotus Elves getting to stand in the snow)
Painted these at work after hours so won't really see how it comes out until tommorow.
