I am assuming her body is at "rest". Take away the shapes and the body looks contorted because the legs are aligned from upper left to lower right. Add that to the shoulders running from lower left to upper right and it makes me feel that the girl is raising one shoulder up really high. Again, that is the only critique I could give because I could not find anything else to point out: colors are great; composition is great; ignoring my critique the woman/lady is great.
It is me: I'm having a hard time reconciling the angles for the shoulders versus the knees/feet.
