Thank you all for your kind words. I can't remember exactly now how I did the armour plating, but I can take an educated guess. The skin was the new Citadel Paint range skaveny named greys; Eshin grey blended with black, then highlighted with Skavenblight Dinge and finally Stormvermin Fur. The armour was probably done with a little of the old foundation paint Adeptus Battlegrey blended with black. Now I would probably use Vallejo Model Colour Black grey (168). However all of the model's extreme highlights was Citadel Codex Grey. Hope this kinda helps, albeit belatedly.
