As a first attempt they're a good start.
1 and 2 the lighting is fine, they're a bit underexposed and the poses need some work (1st one has an 'up the nose' view, and the 2nd emphasises the wrong part of the body - hips away from the camera and weight on back foot would improve it 200%).
The pose on 3 is a winner, I'd like to see her hands but can see why you framed it the way you did. The softbox is a little too close and far back, the light falloff from shoulder to shoulder is the big clue there.
Much that this is the opposite to my general advice; they would all be improved with some careful PP, some skin smoothing and fixing the exposure.
