This head model is base originally on vanilla head model, and I just remodeled it.
And for the skin textures, you can directly download them from Adorest: New Face for Franklin V1.
Installation path: using OpenIV, dont forget to Enable Edit mode.
mods\update\x64\dlcpacks\mppatchesng\dlc.rpf\x64\models\cdimages\mppatches.rpf\player_one
paste the file inside the player_one folder, and Done!
