Breaking The Rules in Phototgraphy

It is always good to learn the past history of doing “things”, but it is bad if you blindly follow a set of rules -especially in art. The above image breaks many rules in photography. It is taken at an F stop that has sharpness issues due to diffraction,it was taken without a Neutral Density density filter to blur the water, and it was taken with a lens seldom used for landscapes (long telephoto). But I didn’t have a ND filter with me, I only had a really long lens, and I needed low ISO, slow shutter speeds, and a small F stop to get the proper exposure for the effect. So I ask you, did breaking the rules work?
