A very geometric concept. However, I think a weakness is the sky. In my view, ityjust does not have enough detail/interest in it to support the rest of the image. In fact if I scroll down the page until everything is off the page and the top of the image appears just above the tallest building, I think you have a stronger image.
I agree - that cropped version is much more pleasing. The diagonal line caused by the water/beach (though broken) provides a very nice split between the two main subjects in this version.
