It may be extremely complex and just an insight but The Elder Scrolls.
In the Elder Scrolls games such as Skyrim and Oblivion, you can adjust all facial features and body shape.
Perhaps instead of species such as Nord, Argonian, Khajiit and Elf. There are the different factions. and you can change facial features. (the bodies can remain how they would in simulation for example, Anglians, possibly large and bulky to remain warm in cold climates.)
