The pastel subtlety of this image is what brings it all together. An otherwise mundane image has been transposed into a dreamy and captivating tease on the viewer's imagination. The softness of the image is in stark contrast to the model's piercing stare, which draws the viewer's eye to a central focal point. Composition is spot on, with the model's eyes appearing in the appropriate quadrant of the image. The only distraction I find is the piece of wood panel to the model's left, running from the upper portion of the chair down to the bottom of the image at an angle - a minor distraction, but one nonetheless. As with all of your images, superb artistic capture of a moment in time.
I love the soft colors and the angel of her body in the chair. It looks relaxed, yet as if something more is about to happen. I like all of the furniture as individual pieces, but it almost feels lopsided. If her chair had been in the opposite position, it seems like you would have balanced it and been able to give a more soft glow by using the window and chiffon window treatments to play into the soft feel of the picture.
As for the model herself, I find the expression on her face is leading me somewhere. It is sexy but almost questioning. I wish you had edited the dark shadow (maybe smudged eyeliner) under her left eye to make her look less tired. And I feel if her lips had just a hint of gloss, while keeping with the soft nude palate, would make them more inviting. My last critique would be her hair. The color seems like it should be richer since it, other than her beautiful brown eyes, are the only bit of dark or real color in the piece. Her hair almost seems dry and brittle, like it's missing it's luster.
Overall, I love this piece. She is stunning and effortless. I love the lace chemise, the set pieces, and the unconventional pose. It's incredibly sexy, yet completely tasteful and really accents the beautiful curves of the female form.
