The hair looks very nice, I don't think that really needs any editing.
The hat is almost there ... Clean up the shadow-color on the brim and add a little more highlight on the pointy part.
The bodice(?) under the dress is mostly just a filled outline. Use some selout there.
The ruffles on the dress look strange to me. It looks like it poofs out, then "tucks" in, the poofs out at the end. May want to make that less drastic.
The boots are almost there, but the fact that they have equal shines in the center points to a bit of pillow shading.
Oh, and if you want a nose on her, make it more defined, as it is, it looks like a really high, really small mouth.
