Very nice paint job.
At first I was not too sure about you not painting the wolf head on the thunder hammer the normal gold or silver but the more I look at it, the more I like it, gives the impression that the hammer head is made of an opaque material and the wold head is carved in, not stuck on. So did you do that on purpose or just forgot to paint it?
I've been using Drakenof Nightshade for my recesses, but find it is too dark without mixing. I think I've tried every wash and shade that you can buy from every paint company and I still can't find just the right blue/grey.
I paint my power armour Fenrisian Grey and then highlight with a 50/50 of Grey and white, as I prefer a much lighter blue (as real sky blue), so the Nuln Oil or Agrax Earthshade is way too dark as a shade for my tastes.
