Deckard Project Continued (shape key testing)

Coming back to this project thanks to a commission to use my Deckard model in a short film :D! For which, I need to finish things up.

So far I have added:
A posable body, Deckard's shoes, Pants (still basic), the PKD Blaster: https://www.artstation.com/artwork/vJKYR6 , and now I am working on shape keys and shape key practice. The shape keys are being implemented on the low poly to try and see if I can get away with texture set for his head rather than transitioning normal etc...Much of this is practice/study but I am having a blast at the different looks shape keys can get achieve.

So much fun.
