The hips start too high. They also have more loops than pretty much anywhere else, maybe take one of those and define the curve of the ribcage too?
Put more polies into the arms, these are way too shapeless. It's bizarre to have very small details like the definition of the pectoral/shoulder and completely ignore things like, you know, a middle loop in the upper arm.
Breasts are silly, get reference.
As Ashey pointed out in a wholly unconstructive and useless manner, her butt has some problems -- either add a lot more polies to define that form properly or just get rid of it entirely. Going halfway is just going to get you nightmarish gouraud shading.
The texture is soft and muddy. Reference some other diffuse only weapons and dig up some tutorials if you need. Examples of what to aim for ->
