Nice photo~ I like the contrast in the values and the shine just plays off very nicely off of her suit. The whole outfit just makes the photo a lot more intriguing because on the one hand the black accentuates her figure on the other hand its fun to be able to try and make out the reflection upon them. I like how the background is soft and glowy but just one thing about it: it's a lot more so towards the bottom than the top. This makes it seem more surreal towards the legs of the chairs and I can see bottom of one of the legs and it almost seems as if the chair is floating on air since the ground blends into the background in a gradient. One thing I noticed that you could be careful about is the hair. On the top of her head it looks really nice and silky but it doesn't look that way towards the darker areas where it hangs down. It looks rough and messy. This happens because it's in black and white and the different highlights playing with the shadows causes that to happen. To fix this you can see if you can either 1. paint over it or 2 find a way to smooth it out or 3 darken the area. Different methods work for different photos so just play around a bit. I like her expression and the contrast on her face. It's soft but at the same time not too much that you can't tell her facial features. The only reason I didn't give you a higher score on vision and impact is that even though you can tell she's looking at her boots, it's not that intriguing of a stare. And even though the focus should be on her boots and her expression, it's hard for me to tell just what message you're trying to convey. Overall, though, nice solid piece. She's a really good model and it was fun to try and see the background through the reflections
Starting with the model, I think this image works very well to present the model in good light. She looks mysterious and sexy, and most of the crucial features are visible, but not standing out too much; When looking at the shot you come into conclusion she has amazing body, but it's amazing on stylish fashion, not in-your-face.
The contrasts on the image add lot of depth to it; her soft and natural face and hair against the shiny and industrial surface of the suit, her provocative clothing but very classy and humble look, black of the suit against the light skin and background. Contrasts on several levels, and they play well together.
The pose is also pretty good; natural enough that someone might actually position herself like that, but still works to present the body and clothing in admirable fashion.
What I would do differently are the details of the background. The odd white stripe on the left is too fuzzy to work as a detail, too sharp to blend in. Also, the hips and torso area could possibly be enhanced. Now it looks a bit like her chest was actually leaner than the waist, but this is a minor complaint.
Also, the pose is possibly a bit unoriginal. If I dropped this into stack of other high quality photos displaying slim women in black PVC, the pose and composition would not make it stand out. Her face and hair could do it, tho.
Also, bonus points for not showing boobs. I definitely would like to see them, but too often when depicting sexy women in PVC the display of boobs approaches corny. So just leaving them not showing lets the imagination of the viewers do the trick, and avoids this one pitfall. After all, what you don't show is even more important than what you show.
