Modelling one hundred years on ideas

the remains of people found at Pompeii thousands of years after - The volcanic ash preserved their
bodies, depicting their final hours before their inevitable demise.

As my map is based around the destruction caused by an erupting volcano, I have an idea for my final video.

for the first section of the machinima, show my model within the crysis environment in the past before the damage. Then have the volcanic debris hail down upon the structure (possibly get some AI bots running away if I can manage it) - This will show the building getting damaged somewhat from the lava rock storm falling upon the Pompeii like setting - By adding ash floating down upon the barcelona pavillion it will add more of an effect to it all.

Then skip to 100 years on, having hardened rock textured people laying down on the floor in various positions attempting to take cover - similar to this photo. It is known that during Pompeii ordeal, Mount Vesuvius erupted, taking out the entire village. As people attempted to take cover, they suffocated from the volcanic ash in the air, and were left laying there upon the ground. However, the volcanic ash hardened around several bodies, preserving them for archaeologists to find hundreds of years later.

I think if I were to model some basic human shapes and apply a darkened concrete/ash like texture, it could add to the overall effect of the environment and the subsequent assignment concepts.
