A little known fact - I don't like painting marines. I don't like that they are all one color primarily, and I don't like the large flat areas of their armor. I also don't like painting metallics. I wish I were a better painter and then I might be tempted to do non-metallic metals. Alas, I must work with the abilities that I do have.
Here is my attempt to do something non traditional with grey knights. I went with gold and made use of P3 armor wash for shading. I must say it is a wonderful product and does a pretty neat job of shadowing the joints of the gold. I used burnished gold and mithril silver for highlights.
The base is from Micro arts and I am choosing to go with a stone look to contrast with all the gold.
Well, before I paint up an army like this - what do you all think? Go with it, or trash it?
