Because it’s more convenient than separately linking 72 skins. Like with the custom skin set I’ll just leave you with the -link. If you’re not sure about which texture you prefer I uploaded extracted textures of each 8 faces here for easier viewing than my gif above. That’s not all though, I did the crazy thing and made defaults with each 8 faces so you can pick whichever facial features you want, you could even mix and match different faces together into a set if you wanted to. As requested, defaults of the previous Skin set I posted, the natural colors each has two options for color but Alien only comes in the green pictured.
