Hi, with my amateur expirience in photography specially in nude photography I can suggest only the following:
the posing of the model here it is much much better then the previous thread you shown
the light is a bit flat for this kind of work, I would use much contrast light and with backlight for example
the chair is excellent for work, I like it very much
the background i do not care so much as it is and it could be better if it was different: black, or white or gray.....
Also the model is really attractive....
Give us some more...
