I don't worry much about rules, I do what my eye loves best. and my eye doesn't like dead flowers, for example, though I've seen them photographed by others and it didn't bother me. it's their art. I chose this photo because there was a huge blue crane in this picture, if it wasn't for that disharmony I would have probably photographed more of the houses below. I'm aware of this rule and I'm trying to let go, but it's a feeling of disharmony difficult to overcome.
