Looks good!! The proportionas are all right, or so I think anyway! Only one thing bugs me.
Something about where the leg(s) join up to the torso, its really awkward. It seems that the left leg (our left) is out too far from her body, maybe try bringing it in closer, like, tucking it in more... I tried to do a redline for you but I have a mouse and it's too shaky.
The best way to fix this is to find a picture of somone in that pose (or close to it) and look at how the pants fall, and how the leg looks.
This is a really nice picture!! Hope I helped somewhat!
