Fabulous job on the sword, and the dark armor get snaps for difficulty and being well executed. A tricky model concept-wise that you've handled beautifully!
I think this would score higher if the base wasn't so awfully simple. Because the sword is just amazing, it has this somewhat uncanny feel to it, as if it's from another world. And I like the glow about his helmet. Someone lit a candle in there? :)
