Could use some work
It's not a bad piece of art. Probably better than anything I could draw freehand, which is why I only draw in Paint.
You should probably do some work on the anatomy. The arms are different lengths, and she doesn't appear to have a chin, or feet. Not sure why the hair is see-through over her eyes?
The eyes are of different size, and the colors are a bit bland. You could maybe work on some shading, it's really not as hard as it sounds.
You could try adding a light source, and add some sort of "shine" to different parts of her. That alone could do wonders.
