I agree with Pooky-chan - the downward cast of his helmet makes him look regretful, or perhaps contemplative. That such evil exists? That violence is necessary to defeat it? Regardless, it's an interesting detail, whether you intended it or not. I love the lighting and the effects surrounding the warrior, however. Clear, clean, and concise without being overbearing or too obvious. Also, it looks like there's a chain surrounding his gauntlet, and his 'sword' is just plain awesome. The level of detail in the environment is impressive, from the pillars and hallway behind him to the play of shadows and light on the ground, it's all excellently done. All in all, great work.
