Here's my thoughts on women's proportions...
Tits: Don't be greedy, a handful is all you can use anyways. If they start to get bigger, they generally have those nasty bologna nipples.
Ass: Shapely. That's it. I don't want a flat ass and I don't want a rhino ass.
Legs: Calves I really don't give two shits about. As long as she doesn't have cankles, I'm fine. She needs to have some nice thighs though. I love to rub on women's thighs.
Face: Definitely the most important. This doesn't mean I won't date anything other than a super model (obviously). But I mean, a face is the main point of attraction. It's what you see first. You HAVE to be attracted to her face to make it work. As long as she doesn't have something that sticks out, like a gigantic crooken nose, then it's all good.
So in conclusion...
Face > Ass > Tits > Legs
