Not bad, the balance and pose are good. Immediately the issues that stand out are the shoulders and the hips. The shoulders on a woman should generally be narrower than the hips. And the hips should be much taller.
But more importantly I though I'd talk about the process of constructing a pose. My first issue with what you're doing is you're thinking of it as "drawing an outline." The human body does not have an outline, an outline is all of the contours of the bodies structure that happen to sit at the edge from this viewpoint. You also seem to really stick to the outline once you start colouring. When I work the outline is just a reference I keep underneath, you should always expect that it is incorrect in some way or another and additional time spent with the piece colouring and shading should make those mistakes clear.
So what makes a pose?:
The most important thing, and the line you should ALWAYS start with is what I've drawn in black. This is called the "line of action" and it represents the balance of the pose and the direction in which the weight shifts as we travel through the figure. With some practice this should be easy to observe.
Secondly you want to place the shoulders and the hips as I've done in purple. Generally speaking the shoulders and the hips mirror each other, this is called "contrapposto." My life drawing teacher often told us to imagine the torso as an accordion, one side stretches, the other side compresses.
Thirdly are the "thrusts" of the body parts. These are represented in red (you can add more to other body parts like the head, hands, feet, torso, hips etc. if you need to.) This is essentially the direction that a part is pointing. You need to imagine a straight line going from one end of the part straight through the centre to the other end, in 3d space. This helps get the angle of the body part correct and is also useful in foreshortening. If you're finding it hard to imagine think of it like the "bones," or as my life drawing teacher gruesomely put it, a skewer stabbed through the centre of the body part.
With these things you can create what is essentially a stick figure that accurately represents the proportion of the human body. The next step is a bit different for everyone but what you want to do is hang the masses of the body onto that stick figure. This is where you can put the skull, ribcage and pelvis in, which inform where most of the rest of the muscle/ fat etc. should go. There's no really simple method of explaining all of the different masses other than through extensive observation. Learning what the bones and muscles are helps you to decide where the lumps and bumps need to be. You should always be thinking of the internal structure of the figure, what we see is merely a representation of this. Also mostly I just wanted to talk about process so my drawing is very rough and has plenty of anatomy issues of it's own, don't follow it too closely
