I have this stinging impression that you don't know the parts of the human body in relation to each other. Are you sure you aren't just drawing blindly with or without reference?
You should give up foreshortening or any of that complicated stuff until you actually know how the body looks and feels like.
http://artists.pixelovely.com/practice-tools/figure-drawing/I recommend you do gesture drawing. Nude models only, 2 minutes on each pose. Do it for a few hours and maybe you might get a better grasp of the shape of the human body. That is not to say that you shouldn't study human body and proportions, because you're obviously lacking both in your drawings. That's clearly and painfully evident from your many drawings, like

- Head is clearly too big
- Collarbone looks as fake as it can get. It's a curved bone that starts where the shoulder and torso connects. Get a skeletal photo and you'll know what I mean. It definitely isn't comprised of two arrows.
-Your shoulders seem like they're just attached to the torso with glue, and that's made worse because of the sharp armpits.
-Character is TOO SHORT. That's not a lady. That's a midget.
-Limb sizes in relation to each other is hella borked. Her right forearm is incredibly short, and even if you were aiming for foreshortening, the hand failed to convey that because of its orientation. Calves are as fat or even fatter than the thighs.
-Torso curve/hourglass shape seems to be done with absolutely no clue as to where it should curve.
-Navel(I'm assuming that's a navel) is in the wrong place.
-Mound of Venus is too wide. It's not just a "V" shape, there's a whole lot more to it that you have to understand.
-Hands seem incredibly lazy, because I can't see any effort put into it. Fingers are basically sausages, and the character's left hand's fingers seem to have only one joint.
-Feet are skewed and have no shape or form, as are the hands.
Bottom line is, you don't know how the human body works, and you need to study how it works. You draw tiddly bits like navel and collar bone, but you're just slapping them on without regard to their placement or shape. I'm not seeing a 3d figure, I'm seeing a flat bunch of curved and straight lines. Mayhaps you are improving, but you are making mistakes that shouldn't happen if you had clearly read and studied the resources that Kaze_Senshi gave you.
