Well, those weird, gigantical eyes... her right one seems to be trying to escape from her face. And the head looks a little on the 2D side. But you seem to have a decent grasp of proportions and shapes. You know where muscles and curves are, and that's way better than most beginning artists. So, it's pretty good for a first start. Just keep plugging away at perfecting the individual bits.
Also, facial practice. Just draw like an entire page of faces. From what I can tell of this one, she looks more befuddled than anything else.
