I was thinking his hair looks like the back of a chicken, like fluffy or something (very deep, I know). This guy's design is more simple and focused on his comfort at the moment of a fight. He is so confident in his skills that he barely wears any real protection and doesn't care about tattoos or accessories like other ones I have drawn.
Here are other devil warriors I have done ;P

Sometimes I draw with a lot of layers, other times i just use layers for the lines, colors, and shading. I don't really detail my drawings as you may notice
It looks really cool! Keep that great work up :)
Thanks!
