Well...
The face and neck are too fat for her body. Way to wide. Just re-doing the face and neck alone would make this drawing so much better.
I like how you've incorporated her possesions into the background, and the coloring/shading isn't half bad.
Buy one of those little wooden mannequins, and practice drawing the human figure from all angles. After you have sketched out the basic proportions, then you can start to draw on clothes and details. Apply this method of working to your anime style characters, and you will find the end result is more natural looking.
Practice makes perfect :)
