As they said this kind of thing is tough. What stands out to me the most is how stiff and rigid the upper body is particularly the shoulders and breasts.
The arms could bend slightly at the elbows, this will also help with deformation during animation, you'll likely need another loop or two there as well. The shoulders could slope a bit more gently to help soften the sillouette.
The legs a bit awkward because the knees are so close together compared to the wide stance of the feet. Pull those out a bit and she will be more balanced.
The shape of the breasts is improved, but for their size, they sit way too high and close together. Remember with size comes weight, they should pull down more and turn slightly outwards, right now they look to point straight out. If you put a tight bikini top on they could be held up high like that but they would still need to be turned out a little.
These are far from perfect but you get the idea, hope it helps.
