For portraitphotography contest. Four children's moods in a few seconds

Kids, they're not adults. Their perception of the world is so flexible and changeable that sometimes you just do not have time to watch the changes in children's mood. However, the camera will not lie. These pictures I took for half a minute five years ago. On them my daughter near a Bush of rose hip. Just look at how quickly it moves from the state of interest to the mood of resentment, then joy and cunning. No, we adults can't do that. No more kids!
