Assuming you used flash for this one.
I find that using a flash without any diffusion, at least on portraits, results on a very unflattering light MOST of the time. Sometimes you can get a cool shot with it, but for general portraits I suggest using a soft box or umbrella just so it's not so harsh. Notice especially on her cheekbone and hair where the light is very harsh.
If you didn't use flash, I'd say use buildings and angles to maximize your lighting available.
I'd say a 6/10. Focus is smack on, and the pose is interesting to say the least.
One from earlier today. More of a playful edit going on.
