Honestly I just feel like I'm out of my depth at this point.

I darkened the contrast on her skin, but at 100% it still isn't very noticeable in the clothed version, and at larger magnifications it looks more like a skin rash to me. Plus I don't really know how to shade the legs with the dress on, adding shadows from the dress looks way too heavy, but without a shadow the natural shading from the shape of her legs look odd coming out from beneath the dress.
I thickened up the arms as best I could while trying to keep her on the slender side. I think she looks a little too muscular now, especially her right arm, but I'm not sure how to fix that without making her back into a string bean.
I moved the hips up, although the difference is pretty minimal. Especially in the dressed version since the dress pretty much covers all of the detail work around the hips. I also widened them a bit near the top, although not much: I tried widening them more noticeably, but that forced me to spread her legs further so that her legs didn't turn into Chun Li's legs. Spreading them further put her into a kind of doofy-looking Megaman pose, though, which I wasn't a huge fan of.
The shading on the dress is a lighter color now. I tried making some crescents to add flow to the hanging part of the dress, but I couldn't get anything that looked natural. So I looked up some reference images, but all of those had more of a vertical ripple, at least in pictures where the models legs were relatively unbent like my character's are. The dress still looks quite flat to me, though, and I'm not quite sure how to add in detail unless I add a design to it. Maybe just reworking the entire pose would make it easier to add life to the dress, having her bend her front leg or something.
I have no idea how to work with the shoes. Maybe just scrap them altogether or make her feet a lot bigger. I couldn't figure out a way to outline them without making them boot-like, which doesn't really go with the dress. For now I just turned them into regular heels instead of open-toed ones, but I'm not too happy with the result.
I just don't like the eyes. They just don't seem to express anything, and barely look like eyes unless you zoom in. Maybe I'll just give up on the current style and give her a proper face.
