There are two kinds of Minotaur, the classical monster and the species. I think they should be entirely divorced from one another, with the species perhaps given a different name.
The monster is a man who has been cursed. The design should reflect that. Mostly human (or elf, dwarf, halfling, etc.) with a bull's head. Human feet, maybe a little extra hair, and if a woman is cursed, she keeps her breasts.
The species is a humanoid bovine. Here, the hooves and fur are proper, and the women should have udders instead of breasts.
Both of these designs have a place in the game, but they should be unrelated to one another.
