she looks good. you get your use out of that wallpaper . . . i would be tempted to make a portrait series in front of it and then hang them on a wall with that same paper. i think the selective coloring is poor in the second shot, but i'm also biased against it.
I Love the first one. Beautiful eyes. Can you do anything about the tan lines? I agree with the second shot. It all looks very blue to me. Unless that is the look you were going for. Nice shots though.
They're all good shots but the PP has some issues. Get rid of the selective coloring it doesn't add anything, and on the one of her jumping it looks over sharpened, did you use high pass? Tone that down or even don't use it at all. Besides the PP they all look good.
