Okay, well, there's a few things absent here.

- No shadows for one, would improve greatly here.
- Ermac is most definately not inline with Kano at all.
- Ermac's orb needs to be faded out at the edges, makes it look more "special", or something . At the moment it looks like a solid object.
- There would most likely be a little more blood produced. Kano has been stabbed at force, mind.
- An effect or trail on/from the sword would be good. If there is one, I can't see it.

Good things:
+ Lifebars are fine.
+ The chosen sprite for Kano fits perfectly.

I think you're using Ermac an awful lot in your fakes, lol, and he's always in the same pose, using telekinesis. Would like to see something different (like the MKDA Sub-Zero one you did).
Keep it up.

Ok, well I think you are using Ermac a bit much. And you also reused that same effect on Ermac's hand here again, just not very original feeling. The fatality idea is actually interesting, but a different type of pose is something you should defiantly look into now.

Again, you did well with the lifebars, but you excluded shadows. And I still don't like these mugshots, just too big. Blood is almost absent here, there needs to be alot more, perhaps some spurting out at places.

The sprite for Kano was a very good choice, but you need to level Ermac with Kano. Again, my greatest suggestion to you is to stop using Ermac in this pose for awhile. If you like telekentic fatalities, why don't you try to make a Kenshi sprite? All of these Ermac fatalities are decent, but you need to tap back into some originality with his poses.
