Does anybody know what the best way is to paint them?

As with other whites. Start with a darker grey/blue (I´d use grey for ghosts) and highlight up to skull white :).

You should use transparent paint, so that you can see through them. :P

Seriously, though... do as Tyrion said. But I, myself, never bother painting several layers or use techniques like drybrush. I just undercoat and paint.

I didn't like blue so i used green like the spirits in lotr3. There is something missing but i don t know what... please tell me what you think and what i should do to make the look better.

There needs to be a lot of contrast. It looks too mundane, too normal with subtle highlights. The recesses should be bright green, the outside light grey. I'd but another highlight of white/grey on.

Why is the army of dwarves dead spectres. Theyre not that grim.

A little fluff, if you would.

Here is some of the fluff, it's the background story of how he became a he is, not how it is possible... <_< I'm still thinking of a way to explain how it could happen.

The story of Peotre Thorgrimson of Varn Drazh (black water)
-1136
Peotre, son of Thorgrim the brother of Kadrin Redmane leads a rescue expedition from Karak Varn to the shore of Blask Water where the mule train of Gromril ore got ambushed. Thorgrim joined the transport because he was Redmane’s best warrior at that time. Many of Redmane’s best warriors had died while retaking Karak Varn. Peotre found his father and his uncle slain on the shore of Black Water serounded by death.

Rangers had reported that the greenskinn horde where by the river 5 miles east of them. So they marched toward the greenskinn horde. The dwarfs knew they where outnumbered and tired from the long march to Black Water but they where firm to collect a grudge that night.

The dwarfs fought fierce and many greenskinns fell under their axes and hammers. But the orcs where to many. When the sun rised the remaining dwarfs had been pushed back to the lake. The fight got to its end when Peotre, the last dwarf standing recieved a lethal thrust in his stomach. Covered in blood he fell to the ground. Peotre swore vengeance to all dwarf foes while he coughed up blood. And with his last breath he shouted to the sky that not even death would would stop him to do so... .
