Welp it is kind of awkward to review stuff like this but ye..
The only thing I would say you should rework is the legs / ass part. As far as I understand you wanted to go for a stocking like look. I think legs are just too dark and lack shading / contrast. When you want to show certain details especially in the curvy areas shading makes a massive difference. These colours are just too similar and they do not expose what they should enough. (at least from my point of view). Just not enough details there.
Other than that, it looks really well done and I dig the rest of the colours.
Also I like how you drew her face.
Overall nicely done!
