I think I see something very interesting going on here. First, playing a game like this with satan or death itself is bound to make anyone nervous. The idea behind the scene is right on.
Now the technical stuff. The glowing eyes of the death character are cool. I wonder how red colored eyes would look. Michael looks good, thoug to no fault of your own, the way the clothing fits him it looks like he is a C-cup. His pectorals look like breasts but it is due to the way the clothing model fits the Daz model. I would suggest changing his angle enough so that we can see his face because it's Micahel's face that will tell us what the emotional stakes of the scene are.
