Great crop, nice shot. For me the soft effect doesn't work here. The models skin doesn't appear to have anything you need to hide, I would get that detail from around the lips and fingers.
An interesting way of staging this habit. The soft, soft focus still allows us to see the fingers, lips and teeth. I like the lighting and exposure very much. It gives the habit a rather dreamy quality.
Too out of focus for my tastes. Was this intentional? It looks like you went to the trouble of setting up a light source and creating some nice shadows but then only took one blurry shot and submitted it.
Very pretty photo. The soft focus is nice but seems a little too blurred around the center area which should be more crisp since it is a main focal point.
I would like this much better if the hand were in focus. The composition is good, I like the lighting, and the soft pink of her lips being the only color other than the flesh is a nice touch, but without using a proper depth of field to create a focal point, this turns out to be just an out-of-focus shot.
