The background material distracts, like Danamo said. Would you try a material with a very fine weave that's barely visible? It also looks very flat. Is it meant to be chainmail? The lighting is very harsh, maybe darker/more subtle, with bright flashes added in postwork, or a bright light reflecting from just one bit of the edge? Maybe do two renders, one with reflected lights, one without, then layer in PS and erase all reflections except here and there? Lovely sword.......might work if you set up a scene where it looked like it was casually dropped on a pile of chainmail, rather than hanging in mid-air?
