I see your inspiration, but, like some of the other comments, her shorts kind of ruins it. Overall its incredibly executed and the detail is amazing, far better then I could ever manage. However, her shorts just take me out of the image, they are unnecessarily low, falling off even. I think that a better choice would have been to have the shorts high, with a little behind curve peeking out the bottom (pun not intended) and the tattoo peeking out the top, plus a belt for that gun? she currently has attached to her shorts, which makes no sense to me whatsoever.
I know you said Boris Vallejo, but personally I see a lt of Dan Luvisi's attention to detail in your work, though your own compositional style is a bit more unique. The smooth, chrome textures and erm, pose of the character is quite Vallejo-esque, though.
