This is my first WH FB Orc. To my mind there is no difference with WH 40K Orks except guns.
I've decided to use "Dmitry's style" here :). He didn't publish his last minis on coolmini but he has a loot of really good works. I tried to repeat his Оrk in my interpretation. He called this technique "speed painting" but I spend a lot of time for it. Before I wanted to use such kind of metal for my Tau Crisises and Broadsides (five of them are waiting my hands) and now I think about how much time I will do it! :) But eyes are fearing and hans are doing. Now I have an expirience, may be Dmitry will give me some comments, advises and ... secrets (of course, I'll ask hin about it :)). And I can do it!
