You could just change the shading to make it look more like plates for it to suit the head and that, the layout of it looks fine to me oh, and remove the blood like parts on it.

And about the set itself, I love the detail and the ultra high-quality, but you could cut down a small bit with the glow like things near the wrists, too much of them don't suit the head that well imo.

Must say they're really minor flaws, and me going a bit too indepth.

Pretty great work.
