Portraits

This week assignment was to make portraits. I decided to make them in the park on a cloudy day. It was very cold and my model (my sister, Atena) was a great sport. Some of the pictures where done with addition of reflected natural light onto her face and some where not. Some of the pictures of her face got overexposed and I'm not sure why. Go to my Picasa pictures by clicking on the slideshow and let me know what you think. Any input will be greatly appreciated.
