The blood is way too overdone. Plus, not all the blood is the same shade. Also, don't you think Kahn should have some blood on him, he did inflict most of that damage and with all that blood on there it's unlikely that he'd stay that clean. Cage's stance doesn't look like the stance of a man who's had his arm torn off, y'know? The arms also have a weird look to them, they should be limping a bit if they're lifeless. Lastly, is that a skeleton coming out of one of Cage's arm?
Ps: Start using Lifebars, counters, etc. It'll look better.
