good colour matey abd good shot - but i think you critiqued correctly when its been done before. If you decide to redo the shot here are some ideas:
1. use the leaves to form a makeshift trail to the girl in the corner
2. add twist of unsuspecting action ie, a little kid about to drop a water ballon on the subject, or a midflight football about to land on the sleeping beauty
3. Have the girl dress in red (contrasting colours with the green)
just some thoughts, thanks for sharing mate!
