Oh wow, just had a look at the photo, gorgeous!
To try and focus a little better, try and focus on the eyes and, if you have time, play with the shutter release to help the camera focus in properly and keep it as still as you can (or take full advantage of any anti-shake function).
I was playing around with my camera the other weekend trying to take photos of birds in my parents' garden, on the fence and bird table and that was hard enough in the light with the movement.
