The upper part of the body looks great and the overall dynamics is caught very well! I suggest to work more on the lower part, the lines for proportion should help
My favourite lines in this piece are the ones you drew for the hula hoop; they're very soft and fluid and capture the shape well. I think the rest of the body might benefit from a similar approach, rather than the shorter, harsher lines that you're currently using.
Thanks for the advice!
Looks really good
the rib cage looks a bit small, I find myself doing this too
overall really good!
