1.) Keep the lines the same thickness or change the thickness gradually. I noticed on the legs and arms you go straight from thick to thin lines. Your lines will look much neater if you stick with one thickness.
2.) Shoulders do not have humps (meaning they do not go down then up). If the characters hands are not above the shoulders, and the character is not shrugging, the shoulders should in most cases slant down.
3.) If hands are hard, draw fists. Fists are usually much easier than hands and bonus! they make your character look tougher.
4.) Draw circles for the joints. Marking joints with circles will help you one, bend the joints in the correct places, and two, make it easier to draw the limbs the same length.
5.) Basic proportioning. The body is usually longer than you drew it, the arms are usually longer than you drew them. You didn't draw all of the legs so I don't know about that.
6.) Try to use a different layer for color. The lock alpha function is also useful for coloring.
7.) face proportions. Your eyes and mouth are beautiful! Just remember the eyes go in the middle of the face, an eyes width apart. The nose goes half way between the eyes and the chin. The mouth goes half way between the nose and the chin. and don't forget the eyebrows!
8.) The hair is in a braid yes? Well first of all, she has lots of hair on the top of her head and not a lot in the braid, hair should be even all the way around the head.
Well, looks great, keep practicing!
