They're okay shots, but I can't get past that railing so close to the camera lens.. I think a picture from in front of the stairs would have been much nicer. It doesn't look like her eyes are in focus in 2, and the PP (3). The blowing hair is nice in the last one.
Nice shots! Does she actually play bass? Can you tell us a bit about your lighting? Is it an umbrella off to the side?
