Thanks for the comments. Let me explain why such an unusual composition.
After seeing hundreds of postcards and shots in travel guides that show a frontal view of the three bell towers, I did not want to imitate the same. I do have a frontal shot, but I did not want to post it for critique.
Why such composition? Two reasons really.
First, I was trying to create a feeling of glimpsing at this magnificent building through a narrow opening between trees on the left and another building on the right. Just like when one peeks into a room through a narrow door opening. Or, when walking through a thick forest, one suddenly sees a brightly lit opening straight ahead. The trees are still left and right, but one focuses attention on the bright green opening ahead.
This is the kind of mood I tried to create without manipulating/postprocessing the image much, though I agree darkening the foreground objects could help somewhat.
Second, due to spacial constrains there was not much choice how to take a picture - just a narrow passageway between the building on the right and trees on the left. I could zoom in on the towers, but this would have significantly cut them in height. Another option would have been to raise the camera significantly above ground, but I did not have any tripod with me.
Just some thoughts and considerations.
