Looks like your model may have had some
skin blemishes which you might have tried to get rid of -- either through use of a filter, photoshop, make up, or something else...
I also think some of the images might have benefited from a shallower depth of field (e.g. maybe
this one) although it could just be that I've viewing a small image on a monitor
I think the comments of boring are justified to a certain extent and may be related to the material. For instance in
this shot you have a picture of a foot. And its a well done picture of a foot, there's a nice contrast between shadow and light, and the image is sharp. But, well, it's a foot and I don't think I'd hang a picture of a foot on my wall, no matter how good.
The material your model was sitting on also isn't so nice. For instance in
this shot she's sunken into the bed so you see one butt cheek. I would much rather have seen her on a hard material so you see her full body, and I agree with the comment about cropping too much -- I would rather have seen all of her since the face is important -- although I can understand how maybe your model wouldn't want to be identifiable.
All in all I think it's interesting work... Better then I could have done

Good job...
