Did you use metallics, or NMM? I actually can't tell- you are amazing at both, but I am guessing this is metallic paint. If so, I want to point out the way that you used the sky-earth technique with the metallic paints. I think metallics can look good- and do look very good on this mini :D.
As for the pose on the head, I think it looks like he's spinning around to face an enemy charging up from the side, much more dynamic then someone idly swinging their spear around while walking straight.
