Very interpretive renderings ... not much to critique, as it looks like you have "command & control" over what you are trying to achieve.
My pref might be to lower the gamma / blacks just a touch in the first one, and raise the gamma just a touch in the second one ... but that's only going to be personal pref, rather than a nit, given these are highly stylistic.
If you haven't already, I might revisit to give the most credence to the face at where you want PP. When I look at the overall image, I'm pretty good with it, thinking "cool stuff" ... then when I get to the face, I'm wanting something just a bit different, if that makes any sense.
No matter how attractive a lady may be I always look first at the face and mostly at the eyes, which are like a window into her soul or something like that. I agree with Kent.
The second is too washed out, I prefer the first. The mirror effect on the floor is neat.
The middle one is quite nicely rendered ... interpretive, yet compelling eyes and modeled features.
Although, I kinda miss the creative reflection candy to entertain us in the bg / negative space. Maybe a "color shadow" (vs. a reflection) behind her to flex your creative skills.
