I used Vray to render the warrior. Vray is a very fast GI renderer, and with some nice features in it. The only down side would be that there isn't any special shadrs for ex, skin, currently.So since Vray didn't have a pre-defined skin shader, I had to create one myself.

And here is how the skin looks like.
When creating metal, the reflection is very important. So by increasing the colour in the reflection channel on the Vray material, from black to a white colour, you are enabling reflections on the shader, also how much relections, dependings on the colour value.
A high value on reflection glossiness, will result in sharp reflections. And a low value will result in blurry reflections.
