^A couple good ideas there, not so sure about things like eye shadow though, its a risk of causing the game to be a bit too much "The Sims" if we had that in there.
One thing which did annoy me in the game is that you were forced to choose out of a group of faces with set hair/features to play with through the whole of the game, instead, maybe have a few set faces like before, but maybe with totally customisable hair, so you can adjust the length, colour and style of the persons hair/facial hair, for each person.
