Yeah, they look good, though I am not a fan of the 5th one myself. The features are too indistinguishable - it looks like he was just torn apart. Also, though I cannot do this myself, it might be a good idea to experiment with limbs that aren't just close to the body. It will require heavier editing, but I think it will make them look better. In any case, those are just suggestions: feel free to discard them.
