Design! 

Once I was at this happy stage with his propotions, I took a quick render of the figure and took him into photoshop for paintovers. I decided to design basic armour outfits to try and find some sort of direction. I really the style of the first design from concept #1 as I like the wild leather with steel look, that i feel follows the Celtic style. #2 I find too basic (cliche?), although I really like his circular shapes such as the chest buckle.       

On the left- The classic wild barbarian look. On the Right - A more civilized warrior 

I really like the john snow type outfit in concept #2. A brute of a barbarian needs feathers and cloth to keep himself warm in the winter if he is only wearing skimpy armour! I went crazy with the hellish "Hades" (greek mythology, god of war) type character. maybe having 1 or 2 spikes on his armour won't hurt! :D  

On the left - The john snow look On the Right - An evil hell raiser!!

   I shall post up more reference images to bring myself closer to the traditional Celtic culture designs for armour details, shapes and traditions.
