I'd say your technique's pretty nice :3
Great anatomy and shadows, the eyes are just right and while people usually struggle with side views of the face, you have done a pretty decent job!
The contrasts between the blue and the red attracts the eyes but appart from that, you're missing important elements.

It'd be nice to see something with a concept or something more... rememberable. Maybe a nice background or some light plays. Your character looks great but she lacks an important aspect that will make others react to her nicely and so that when they see more of her, they'll say "Hey, I remember that character!"
