Vertical would have made this a nice portrait. As shot, her chin is at the bottom of the frame, and the top of her head is cut off. I do not mind the head chop as much as the chin almost at the bottom of the frame, and all the dead space on both sides of her face. I like the warm, magenta background you used--that looks lovely. She's a cute child. The lighting seems, well, a bit unorthodox...I see an under-chin shadow, and then I see a BIG catchlight very low in the eye, and then a pin-point catchlight...which adds up to a kind of unusual look to the eyes.
