First of all I must say, like everyone else perhaps, your model looks strikingly great for someone who has been up since 4am ;)
On to the show. The overall tonalities of this image struck me best at first. As my eye pans around the image, mostly on her face of course, the contrast and tonalities are spot on. I really do like the approach of using BW for this image. The smoothness in her skin is evident and the texture in her hair is quite rich and pleasing to the eye.
My only drawback is the background. IMHO, had it been all white, this would have probably been a higher rated image. I would probably add anywhere between a .1 to a .3 to this image. It is almost a high key image and I'm quite fond of it myself and so are a few folks here on DPC. There is a hot spot on her left hand but nothing really to downgarde this beautiful image.
Overall I think your score reflects your protrayal of this image for this challenge. I love the image and rated it fairly high (8). Keep on shooting and I can't wait to see more of your work.
A beautiful model. A clarity of texture in this photo allow for me to say that this is one of the best portraits I have seen in some time. Exquisite. 9
i dont think this photograph fits the title of the challenge given... no disrespect but your model does look like she likes what she was doing..... i dont feel the feedback from this image... but the effort i gave you a fair grade
