Working on this model in ZBrush I tried to collect all my knowledge from my previous works.
At this point I already had a little experience with asymmetry, which I wanted to focus on while working on this model. Just like in my previous works I used the polypaint tool in combination with the noise tool to create skin texture. Also, I continued my experiments with using different materials on the same mesh and rendering the transparent shell around the eyes.
While creating this model I was inspired by the work of Max Grecke (https://maxgrecke.artstation.com/), so I am very thankful to Him!
The final picture was rendered in a ZBrush and composed in Photoshop.
