Hey guys,
Calling this one done. I created the whole model with Zbrush and rendered in Keyshot.
I used a back plate that came with Keyshot as it happened to be fitting of the scene I was portraying.
The shell-fish like creatures are called "Players" in the original show - Zetman. The scene is an aftermath of the battle between the secondary Protagonist - Alphas, and these man-made creatures - "Players".
Other than the model and back plate, the rest was matte-painted and put together with purely photos and some underlying sketches.
Thanks for viewing!
