edit

I spent a fair amount of time studying SD3 character sprites back in the day, and so I thought I should throw in my two cents.
The two main issues I noticed were that her head was too square and her body was too broad. One minor but important detail I noticed was that she was an odd number of pixels wide. It seems innocent enough, but it can really make a character look squished or stretched. I think this has to do with:
A) Much like we can spot problems in anatomy automatically, we can spot that same issue because even width character sprites are so common place in rpgs.
B) The face tends to be too thin or too fat, because the space between the eyes should be precisely an eyes width, which usually happens to be two pixels
Other than those main points I felt that a few too many colors were being used and everything in general was kind of blurred together.
What I did was; reduce the colors used, simplify the shading, add more body and depth to the hair, and, of course, change the width to an even number. I also grew out the legs and shrunk the torso/chest area. In my opinion this results in a cleaner and easier to read sprite.
I'm not sure how much this edit will help you, seeing as I took it a completely different direction, but I wanted to give you a different perspective to look at.
