This is my first work, inspired by Demon Slayer - Kimetsu no yaiba anime.
This is my free version, my "fan art"

Printing: Files have few layers, you can print it easily.

Supports: some parts, like eyes, nose etc have small supports that must be removed AFTER you print and attach the printing to the wall

I suggest to use a white background or a white first layer ( a rectangle ) and then print the subject file .
