Absolute on first sight
The model is absolutely amazing, and the pose you have choosen is all but fitting for her character.
I like the big contrast between her skin and the dark, black clothes/hair and sorroundings
Another amazing picture, and a model with a stunning eyes
I think I know what you are going for here. Maybe its just me, but I don't even sense aloofness or conscious detachment (as if to say "Go ahead, make me care."). The sense I get is more like: "Hmm. Did I remember to lock my door when I left this morning?" It's just not quite "right". This, of course, is no slur on your technical skills. They are top notch both here and on the others in this series. The model is just not quite there with you. OF well, just my two cents worth.
