Wraith

I tried to paint a wraith for the first time the other day. I was going for ghostly ethereal look, don't know if I got that look to work though, tried to paint with light colours at first and then give him a wash of Thraka Green, Leviathan Purple (on armour) and in the recesses a mix of Thraka Green and watered down Orkhide Shade. What do think? Comments and suggestions are very much appreciated.
