Concentration Update

I just found a new technique!

So before I made the subject look as if bits and pieces of the stone was falling off. Instead, I was thinking that perhaps I could do a diptych and triptychs where more time progression can be shown than it can through through the twelve images. The images together will show the progression of either the stone surrounding the face or the stone coming off the face. The technique here was I first manipulated the full image to black and white and stone. Put the original image on top of the manipulated image and then erase the part that I want stone. It looks much more natural than that rough bevel & emboss effect I tried doing before. But I would love for some hints and help for how to make something from an image look as if it's being torn off or make it look like there is a layer of an object missing. 

Here is what I was thinking:

But instead of the subject remaining still as she gets turned stone, I am planning on having her change poses to show that the process of the metamorphosis is painful. Which form is better, the one on the left with the sepia like tone towards the end or the one on the right with no filter?
