I The drawing went wrong at the initial stage. Look at the eyes. First, look at the size ot them. The left and right eyes are slightly different. Then, look at where they are. The position of the eyes is off and this is the most common reason tor a picture looking odd. The height of the eyes is unnatural because they are not aligned parallel with the inclination of the face (the outline of the head). It would be the same curved. Look at the completed drawing below.
It is basically the same for exaggerated Anime characters as well. When you can draw faces as cubes without having to think about it, you know that you have improved a great deal.
