Lovely lady!
I can see the Frazetta influence.
My crits:
I think the arms are bit short, quite a bit. I do this all the time.
It comes from you being tied to that pose too much. How tall is she when she is actually standing up without that arching back? Straighten her up and then figure the length of her arms/other anatomy landmarks.
Another fault I do all the time, being lazy with reference. I think you are doing the same mistake. Use reference for anatomical details such as ankles and hands and knee area.
The sculpt is very beautiful, deserves to be taken up that last notch…
Hope my crits are not to vague.
