JaimeVinasComment: I don't see anything technically wrong here at all.
I suspect the subtle things might have worked against you:
As noted, her left-frame foot placement seems awkward & floating--a bit of outboard swivel to the left, showing a little more heel and line of the shoe/foot might have made more accessible, and created a flow into the image even more than you already have. (I just got chewed out, er, constructively criticized, yea that's it, for the "hiding of the heels" in a shot by a pseudo art director so I am extra conscious of that now :-)
The line from her right-frame knee up to her shoulder is basically straight, perhaps not as feminine as possible, and could cause some subtle lack of interest. Her left-frame thigh is blending with her torso, adding a bit of thickness/bulk right there--more so because of the graphic b/w treatment.
Her straight to the side gaze is okay, but the hidden implication is that there is something of interest way out of view, and it might tend to send the viewer right out of frame. That, with her pose, almost suggests something she is tense about "over there" and so there is an unspoken tension/negativity in the image for me.
I like the arm placement, though it might seem closed off or uninviting--but it looks casual and natural to me, almost like you snapped this when she wasn't expecting to be shot.
I like the graphic look, here, but that can also be off-putting to some.
If this basic shot were tweaked with the foot twisted out just a bit, some separation between the left-frame leg and torso, and the model did a slight head tilt toward the frame-right, faced the camera and fired off a smoldering look right thru the lens, well, if she did that, nobody would notice the ankle twist at all :-)
