This is a very good image and I have no real criticism of it.
The framing and blank background is perfectly executed and focuses total attention on the model. The pose is really good, with the crooked legs and body curves really showing off the female form. Her hair is lovely, and her makeup is dramatic. The clothing is bold and the dark color and strong pattern contrasts with the skin tones very well. This is a good example of being extra sexy by showing less skin. The clunky shoes balance the image which would be too top-heavy if she were barefoot.
Normally I want to see skin detail and texture. This image doesn't show that, with the skin tones being washed out and heavily post-processed. It's acceptable in this case because the stark contrasts combine to an unworldly appearance. Obviously the processing on her face was extensive, but still gives a very lively appearance to her eyes.
There are only two things I don't like about this image. One is that the fingernail color doesn't match. Red or even purple would be better, I think. The other is that at this resolution the definition of her hair is limited, especially the few strands on her forehead. But these are very slight problems. Is the model missing a finger on her left hand?
Great shot. Having her pose in this manner (knees together, hips thrust backward a bit, chest thrust forward) has very interesting implications and works on so many levels (e.g. a sense of innocence/shyness - oops I don't want to reveal too much and the presage of a well known bodily function based fetish for starters). Also, invites one to wonder what the view from behind would be. Had to fave it.
