That is sound as a pound! I agree with DF that the base does not do the mini justice. I also think that the red is very well executed. If you forced me to find fault I think that the back of the blade would benefit from a little work as would the yellow 'loincloth'. If you hadn't shown us the back view however, I would be none the wiser! The silver rim of the shield could also be tidied up a bit. Damn nice piece though!
I think it's a very nice job. I just bought this one myself. I dislike the base, but that's nothing to do with your execution, just the unnatural (IMO) looking sculpt of the base. Your reds are good. Perhaps the weapon is a bit too clean for an undead warrior. The loincloth also could use a little smoother transition, I think. Overall a very solid piece of work.
