I created this Oni Mask with my first one in mind. - https://sketchfab.com/3d-models/oni-mask-july-2019-4f9126cdc0d64480911ea4aa0016e330
It is some sort a successor of it.
**This Model is High Poly**
I plan to retopologize it to make it game ready.
Additionally maybe I will expand on the base idea and make a bust / character out of it.
I hope you got inspired by my mask.
