Try cloning out the twigs poking the back of her head.
Of the three, I think this is my favourite, though I can’t think of a reason for the pose. What caused the apparition above her left shoulder? Her arms seem to have more tan than her face and body. The left side of her face is slightly too bright. Try opening up the shadows a little. All of these things are pretty picky!
This is a pretty good environmental portrait. I gather it is on a walkway over a road and the fencing is to keep things from being thrown from the bridge. Amy’s comment was earned.
Cute little chick, big bum. I think this is weakest of the bunch. Lighting is pretty good though. Light could have been placed a bit further from her, but I don’t know if that would be possible in that location.
Doing well. Keep shooting.
