I'd argue that being a virtual model, V4 functions pretty much like a real-life actress. So unless you're creating a character with a specific "facial" look which you'd like to copyright or trademark, I don't see how her having a "proper" face is even relevant.

For example, Boris Karloff pretty much defined the role of Frankenstein's monster so well, that ever since, most Frankenstein's  Monsters pretty much all look alike.

On the other hand, Dracula's face tends to change from actor to actor.
