The pose would look a tad more menacing with the head being pushed a few pixels to the left and the right leg (spriter's view) being pushed up a few pixels, so that the character doesn't stand on one line. The sword shaft seems a bit rough at the moment, but I'm sure you know that
Also, just from the top of my head, since it kinda reminded me on Brolly from EB, did you use his stance as a base/reference there?
