Dynamic Transformation to an Original Creature

The artifact is a real-time animation of a normal human transforming into an original creature. About the creature, I designed the creature which is Cthulhu-like, based on the plants and religion. The creature is more organic and human shaped. There is animation for the muscle pulsation and facial change. Regarding real-time transformation, I used morph targets for the creation. I imported the original model into ZBrush or Blender for secondary sculpting, then utilized morph targets or blend shapes for the transformation.
