The Husks were released in 1.10 and their texture was absolutley perfect. It wasnt just a Zombie Rexture with a Hat like how it was changed in 1.14. The Face had its skull visible through the skin of the husk and then 1.14 released and the husks texture became just the thing mentioned before a bad recolored Zombie with some Husk Features. So the point of skin was to fix this. This is like the first Mob Skin im gonna actually use in Minecraft.
