I have to agree with the previous posters, this is a lovely image.
I like the use of contrast, of shapes and tonality. The balance works very well.
And it's one of the very, very few wide angle images I see that actually justifies a wide angle; too often, people use a wide angle to capture too much, but this time it really makes the image.
But I do keep wondering if it wouldn't work even better if you cropped off a bit both sides. Or woiuld that make it "too perfect"?
