I always have New Zealand photographer Anne Noble's photos of her daughter's mouth on my mind. Both as a series and on their own these photos are entrancing works. When I stumbled across Kawashima Kotori's equally entrancing portraits of his young daughter a similar captivation came over me. His daughter has a wonderful, adorable face that has a new, strange expression in each photo. They are delightful photos.
Check out the photographer's website here (the photos are from here also).
