Hi William
Not too sure about this one either (sorry), it's the pose as Kathy has already pointed out, from my point of view it would be difficult, if not impossible to look alluring in such an uncomfortable position, she looks as if she should be at the starting blocks about to run the 100m in stiletto's! also her right shoulder looks ready to send a punch, but I think she's just clinging on to the stool to prevent herself from stumbling. She has a lovely athletic body, was the intension of such a strong pose to compare her femininity with her strength??
Also it would be nice to see the head tilted backwards to lengthen her neck, instead of the chin brought forward which produces a shotened effect, and stood so that she can really arch her back and throw her head back to create an attractive curve.
To end on a positive note, I like the lighting and the fact that you are trying to do something different from the stereo-typical, it's the poses that need to look more comfortable and less contrived. She will be a good model for you to work with I'm sure, well done again, I enjoy watching your progression, please keep posting .....
Sorry - just one more thing - not too sure about the blue eye shadow either, personally I've never considered matching my eye-shadow to my pants! (but maybe that's just me!!) IMHO a darker smokey eye, would be more alluring, and make her eyes look larger, just trying to help, hope you don't mind my being picky......
