Can definitely relate to what PixelPiledriver is saying, to me it seems that there's not enough emphasis put on the line that is created by both the boob and pectoral muscle.
The waist area, despite the corset effecting it in mind, seems really weird to me. I think it's mainly because of the bump that seems to be a hipbone (which is way too high and "in front" for a lack of a better word), but secondly also because of the belt thingies on her stomach. I understand that the straps are supposed to be slightly out of the belt buckles, but it looks really confusing like this; almost as if the whole belt is warped downwards awkwardly. I would suggest to tune down down the yellow highlight, if not eliminate the whole loose strap part of it altogether.
Still with the waist, the middle green-ish part of the corset doesn't look quite right in my eyes, this is to do with what I mentioned regarding the belts but also with what I referred to as being too "in-front" earlier (part of the dress that looks like a hipbone). I'll try to explain it like this (I'll also show this in an edit further in) but the bump created in there (and the consideration that the dress and corset are symmetrical) implies that the green part needs to curve inwards as it goes down with another bump on the left side created next to it.
Easiest way to fix that would be to simply make it straight (ofc if needed make it curve with alignment to the body).
Small detail that I noticed around the waist but not quite sure what it is, is somewhat like flower decorations(?), could do with some more adjusting but idk.
A bit of input on the arms; the front hand, while I don't considering anything to be particularly wrong seems to me that it touches the hipbone too lightly, almost like it's slightly floating above it. A small thing that I would suggest to do is add a shadow to the side of the humerus bone that is seen (the shoulder basically) to imply that it's facing the front better (you'll see what I mean better in the edit).
With the rear arm there's a tiny mistake with the arm's anatomy (nothing too big mind you, its shape is just too "sausagy") and also the wrinkles that are created in-between the upper and lower arm aren't quite right.
The legs is the part I'm truly sure about, I made a skeleton illustration to help show what I mean. Currently the problem I have with the legs, or just front leg I suppose, is that the lower limb seems to go too back (or too to the right from the front view) and that gives it a really over-the-top elongated feel; it causes the two limbs to look like they're of the same length.
