So I did a different take on this Roblox head, typically Roblox heads have a flat decal pasted on the cylinder's front surface, which fits the cartoony aesthetic of a Roblox character, but I wanted to try a different take by making a more realistic head with 3D features.
I first sculpted the mesh in Blender, and later took it to substance to texture the details on the head, I went for a war face for the expression, giving him cuts and scars on his face for more detail. This utilizes PBR
