I chose Balancing Elements from the given list, because this seems the most interconnecting and this is what I try either I use rules in purpose our unconsciously.
In am not sure if it is possible to use just one of those rules on the list. The rules of photography are related with each other. Some will always occur as focus and frame. Those might be wrong set, but it is impossible to take any photo without. More often than not we use more than one of them in our creations, sometimes unconsciously. I think, that is what happened to this photo. I hope it is acceptable as entry for this contest.
