TheKid965 said: I don't know why, but looking at this again, her right arm seems kinda... off.
The shoulder with her arm rested against her side is higher from her hips than the one where the arm is crooked and hand on her hip, when it should have been the other way around due to perspective (resting your arm like that causes the corresponding shoulder to rise normally). To resolve, the upper arm was drawn shorter, so that both arms were the same length compared to her hips when outstretched. It's hard to tell whether the artist attempted foreshortening or not.
