the first one her face looks to washed out, also i think another angle would have worked better so that you'd see all of her feet, not just part of them.
the rest, the shoulder and above aren't doing i for me. i'm assuming she is either wearing a low shirt or no shirt, either way you should have included more of her to me it would have made the picture look correct.
also the different facial expressions to me kill the pictures even more, shes not smiling which is okay if thats not what you are going for but i feel the only difference in the las two is that the last one her mouth is closed.
hope you dont take it to harsh, just what i felt.
The blurring is part of the PP technique I was using. It is essentially the Orton Effect here you merge and overexposed out of focus exposure with a sharp exposure. It creates a blurring halo effect.
one more things .. she is certainly beautiful... but did she bite her lips before the shooting? at least they appear too dry, if not even hurt.
