Nicely done Morg. As someone having their picture taken, I'd be happy with them. As the person behind the camera, not quite so happy.
First one is on the button.
Second one, I don't like that distracting twig at top right and I think you should have been a little bit at an angle, there's just something about that shot that doesn't feel right as it is.
Third one, it looks more like she is distracted than gazing at something. I think this would have been better taken on the horizontal.
Fourth one is good except I would probably crop from bottom and left to get rid of the part of her skirt where the knee bends and also to get rid of the daylight between the tree and the edge.
Those are my thoughts anyway.
