Step 6: Make it bloody!
Now that you have your wounds and dead hand(s), you need blood! Use the blood spatter effect by flicking blood onto yourself with a bad paintbrush. Put some dark blood in the center of any wounds and then let the red blood flow naturally. You don't want it to look painted. We are going for an organic look!
