What I notice is that the "base" of the portrait covers almost the entire width of a horizontal frame, in light-colored fur against a jet black backdrop, which gives her this immensely wide feeling, made more wide by the hair streaming outwardly toward the edges of the frame. This is what is called an arm pose, but the way the arm and hand are positioned is not delicate or feminine, and the head is rather a small element atop this massive expanse of the white fur on the posing table, and the rabbit-fur wrap she's wearing. The things I noticed were the odd horizontal framing, and the direct, square-shouldered positioning to the camera/lens axis, which makes her look very wide. The cloning-in of the fur makes the width look much worse; leaving both arms in shows more of "her", and lessens the width-of-the-frame effect that the second, cloned-in fur shot creates.
Overall, this is just not a good framing or a good arm pose. Her chin is below the middle of the horizontal frame, and the hand and arm under the chin , both,appear very big: her arm width at the bottom of the frame actually measures out to be wider than the widest part of her face, which indicates rather severe foreshortening and enlarging of the width of her arm, indicating too-close a camera position, and/or too-short of a focal length. To me, that is the second-worse thing: the measured width of the arm in comparison to the width of the face at the widest part (foreshortening and exaggeration of the arm and hand).
