I agree with Bendover.
Amazing head. The metal work is great (except for a few lines at the back). The attention to detail is awesome, and I love the concept. An entire set with this will be amazing. Though it'd be too hard, joints would be sick (though not many people have/like joints). I think the dragon looking pieces in the center are really cool on the flat, but on the Tori, they look too centered, and it looks too reflected (that's because it is). The flames/smoke look less like they're coming out of the helmet, and more like they're just floating there. I say, change the flames up and do a soft glow or something. The head looks best from a frontward sideways position. I know I've said this before (and you're probably sick of it by now lol), make the sides slightly asymmetrical.
Love it, can't wait to see more.
