Hi Jeff,
The model itself looks great! I agree with the comments already posted so I will not repeat them.
The one thing that needs work I feel is the photography. Since this is the web and not a contest where we can walk right up to the model, photos are all we have to judge your work. The better the photo, the more objective we can be and the easier it is to concentrate on the model rather than the picture. I know this is not a photography critique forum but there are a few things that you can do to better your photos:
The depth of field on the photos is rather shallow. Try stopping the lens down to at least f/8 or smaller. This will require more light. You can do this with a longer exposure (not recommended as it can induce a blur if anything is bumped and can cause color shifts in the negative) or you can add lights. I personally prefer strobes bounced into an umbrella or through a softbox but photoflood bulbs in reflectors work very well also. They can be found in any photo store and often places like Ritz Camera in the mall will have to them too.
The other thing is perspective. These photos were taken with a wide angle lens. This distorts perspective, making things in the foreground appear larger in comparison to things farther back. Try moving back and using a longer focal length lens. When doing things with film I use a 55mm or even an 85mm lens. This flattens the perspective somewhat and gives the photos a more natural appearance. Keep in mind, the longer the focal length the shallower the depth of field for any given aperture.
Lastly, the wrinkles on your sheet are distracting. You can iron them out or go to a photo store and get some seamless background paper. I use white for a couple of reasons. One, it is a very neutral background and two, it will reflect light up and open up shadows under the model.
If you are using a digital camera, you are limited to probably an f/8 minimum aperture. This is usually sufficient for most applications. Try to keep your zoom mid range to correct the perspective problems.
This is the set-up I use. It is a little cramped (an understatement if ever there was one) but it works well.

Again, great model, keep up the good work!
