The angle of the light casts odd shadows on the model's right arm, highlighting wrinkles and making her look rather old. There's an odd blueish color cast on her arm that I find a bit distracting. Her chest, neck and chin have far too little texture - go easy on the NeatImage &/or airbrushing. The light is a little harsh; the white suit is overexposed on the bottom right and almost blends in with the background, while the side away from the light is awash in deep, harsh shadows. Moving your light farther from the model, moving her a bit farther from the background, and possibly adding another, dimmer light from the other side would help to correct this.
The ring is distracting from the rest of the color scheme here, and the arm is unattractive compared to the rest of the shot showing. Just my take on it, but a bit of neat image on the arm would have done well.
Great fantasy shot! The red really offsets the white nicely. There seems to be a bit of noise/grain in the shadowed areas (perhaps intended?) Great composition.
Definitely meets the challenge - good job on that. I think the shadow to the left is a bit harsh, as is the lighting along the right. Perhaps the light was too close to her? The focus seems too soft - but then you are demonstrating kind of a dream, so it works - just not sure it was intentional on your part. Looking at it more, looks like you used NeatImage or some other noise reduction software and hit it too hard, losing the details.
