in this image i tried to stay focus on the main image i had in mind and care less about the apps i was going to use, and that is my typical workflow. Think, Plan and let the softwares execute.
Modelling a low poly skull in Cinema 4D
using ReaperX plugin for Cinema 4d to generate the plated beards
sculpt some details with Zbrush, and also used nano mesh for the cloth
BPR to export alpha + Depth map
used After Effects to generate the background
finally used Photoshop to paint all the dirt and some details
