Strong is the new sexy.
Although strong can take many forms because no matter how hard you train as a woman, without the perfect genetics (or steroid cheating) you simply cannot build huge muscles or even look like that picture. (I know, I've tried
)
I am a fan of body sliders in character creation, as long as they are within the range of "normal". It would be really fun to be able to make your character taller or shorter, and have options as to at least chest, waist, hip proportions, both for male and female characters.
Also better hair (hair that moves would be nice or at least that doesn't look like a plastic hat), and of course MUCH MORE options in the style and color departments.
