As weird as it sounds, Skyrim's facegen is watered down compared to Fallout 3 and Oblivion. You cannot tweak a character's temples and forehead, their eye shape outside of premade morphs and height-width, their overall face shape will always be somewhat boxy rather than have some variation of round, boxy and diamond-like face shapes. It is also quite impossible to make an intentionally very ugly character, which kinda sucks.>4 body types
Not even. In vanilla Morrowind, all humanoid races just share 1 body mesh in MW, with Orcs just having their body mesh stretched at the side axis in a quite ugly way. Oblivion is even worse in this regard, with basically every race sharing one body mesh with the only difference being textures that are not even blended with the head texture.
