OKAY.  ARTISTS!  LISTEN UP!  You see

OKAY.  ARTISTS!  LISTEN UP!  You see that curve you keep drawing that attaches her leg to her waist?  That curve you love to draw so much?  That is her hip.  It is a ball and socket joint.  It rotates.  If the leg is not straight down, the hip should not be either!  Thank you for your time. :)
