This is one great composition! Rather simple, with leading lines to focus on it keeps the watcher very satisfied and at the same time calm.
The technique is also very nice, exposure and metering are just wonderful
However, I think that the main subject it leaning a bit to the right. Is that true? I don't know if I am the only one to see it but if it really leans you could straighten it up in order to look ever better.
All in all I believe it is a great artwork Good work
