If you would indulge me for a moment, I'm curious-- On my D700 there is a 'map' of the colour/tone selections, in a grid form, showing the points of the various settings: Standard, Vivid, Monochrome.... You can set your own points for a setting with the crispness and colour values you want, much like mimicking different films.
Does your D70 or 90 have this ability? My 700 is the only digital I have had, all else being 135 and 120/220 film.
I think this a special work, however the model and the flower gives some strength to the photo, considering the watermark the force of work it really becomes brilliant. For this reason it should be in any photo handbook.
In any photography relating the model with the surroundings is very important, I tried to use the clothes and the background: [link]
Relating throw tones and dof is one of the most interesting challenge of this work, in this case the dramatic framing on a side and the free framing on the other side is also stunning. Pity that not everybody studies the art of the moment, maybe it is better than the old one.
