I would have been tempted to call this 4 dancing girls but your title certainly fits. The high contrast especially in the balloons makes me think of simplicity and how as a child things seem that way. I quite like this photograph. You're in my top 2 for this challenge. Good luck.
the highlights are a little blown, but i can see that this little girl is very sweet and cute, and the moment/joy captured is better than any technically perfect photo. good job.
