The hair looks very stiff, the eyes on the first one are good, but too close together, maybe instead of trying to fit the eyes into where the hair opens up, make it so the eyes are under part of the hair. The lines are shaky and the thinness of the outline makes the drawing itself feel flat. If you are going to draw hands, I recommend either leaving them as stumps, or drawing all 5 fingers. The arms are a bit too thin in the middle and very wide around where the wrist should be. You should look into some basic anatomy tutorials. In the second picture, the shoulders are very broad for such small arms and the torso angles in unrealistically.
