Right off the bat, I see a couple of issues here. First, you ISO is set very high; the D70s does perform acceptably at ISO 800, but nowhere near as well as it does further down. Given that your shutter speed was 1/800, you could easily have reduced your shutter speed to around 1/200 (more than fast enough to freeze any minor movement, even 1/125 would work) and dropped your ISO to less noisy 300ish.
With respect to the image itself, one of the things that sets great images apart from good images is the "little things". In this case the exposure is nice and even, no extrem shadows or highlights, however a fill-flash to provide some catchlights in her eyes would have given a lot more life to her. As well, you have an ideal background, but because it's sharply focused it fights with the subject for attention. Your apeture was almost wide I open, so the best option would be to have moved the model further awya from the background, and had it nice and soft green. If you have one, a telephoto lens would help, as it has a shallower DoF than wider-angle lenses.
2. Two concerns that I have with this image are: (1) The subject is not looking at the camera. Her expression says to me, "Oh brother, how much longer do I have to put up with this?" Not sure if that was the intention or not, but it's the effect that I get. (2) are the over-bright highlights in the upper LH corner of the image; a minor issue, but a distraction nonetheless. Refer to #1 for comments with respect to DoF and backgrounds.
3. I think enough has been said about this particular image.
Overall, very nice. I much prefer 1 and 2, but tastes vary. Keep working at it.
Just my $00.02 worth - your milage may vary.
