I think both arms are off of their proper locations, moreso the extended right arm. I also think that too often your shading follows your outlines, you should try to depend on those less. The sword can be done with shapes in tones and in a more appealing way, the way you have it now, with the outlines and simple shading causes it to lose any material properties. The same goes for the ornamental pieces on his helmet. Quite simply, doesn't look metallic. Also, the outlines on the lips and bright red, in combination with the low-contrast teeth bother me. In general, I think the use of sel-out hurts the piece, as does the excessive outlining, but in general I like the drawing and color choices.
