DRAW ON PRINT PAPER AT LEAST!!!! PLEASE!!! Especially really intricate pieces like this. They deserve more than notebook paper. Lines writing is for writing. The lines are a distraction from the art and notebook paper is just too thin to really work with. So if you have white paper available, definitely use it instead (printer paper is super duper cheap, too).
Now, it's easy to see that you drew the legs AFTER you drew the dress. Draw the entire figure first!!!! BEFORE the clothing. It'll improve your anatomy and make more sense of the drawing in the long run. Also, I know hands are a scary concept, but the sooner the better so stop hiding them!! Next to no one constantly has their arms behind and it's a boring pose. Either the knees should be higher or the calves should be longer. The nose is really high on the face and the face is really high on the head. The inner outline of the breast on the right shouldn't be there at all due to the clothing NOT cupping it. Since the perspective is 3/4, the far should (one on the left) should be less visible as well as the far eye (when things are turned away from the viewer, they get thinner in length ((not height!)).
