Tounge in cheek here brother-tounge in cheek.
Where? I only see knees and thighs and they are dark compared to the rest of the image (nylons-no doubt). The arm is very distracting and she has no fingers to with what's left of her hand.
Really. If you're going to shoot legs-shoot legs. If you're going to shoot torso-shoot torso. They can both be very artistic in their own right but trying to combine the two can be a daunting task. You can try to frame the left by having the model place her arm perpendicular to the floor and just capture half of it while cropping the models legs at the knees. You will end up with an image in the shape of a "v" but it could work. I wouldn't worry about the dark spaces in between as they can also add to the overall dynamic of the image.
Keep trying. You have an interesting concept that I would like to see when completed.
Here's a full pair of legs with model attached.
