Whenever you shoot subjects with strong highlights, or white clothing, be sure to use the spot meter. If you had metered on the light side of her face or her white dress, this whole image would be darker, the colors richer, and there would be no burn out. But you did get a spontaneous body language and expression. The two pillows, two legs, and two arms create rhythmic repetition that draws the image together. You just need to work on exposure an metering here.
