Very nice work. I really really love what you've done here and how you've been able to capture a shot with many different things going on at once and all of it coming together wonderfully.
The first thing I love about this and many great pictures of photography in general, are the colors. The way the colors come off in the background and mesh with everything that's the main focus of the shot gives it a great "WOW" factor, and makes everything look better as a whole. How everything has that pretty color to it with the way things are reflected, such as the waves of water or the building itself is very pleasant to look at. It gives it a very warm, home like feel in my opinion.
The second thing I love is the timing of the shot. It was just right to capture things at the right angle and the right time of day for what you were going for. The cloud formations also have that spread out look to them, which I think helps in giving the already mentioned color of the picture the right amount of saturation for the overall viewing experience.
The last thing that I love is the location you decided on. I'm not quite sure if I can put my finger on it, since the idea of what you decided the picture's focus would be (a building middle and center) isn't breaking new ground, we've all seen it done before many times. But how it's pictured and the surroundings of what you decided to capture is what makes the picture not only intriguing, but just very beautiful to look at. A place that normally might not seem all that pretty on the surface was made pretty by how you captured it and the decisions you made about the timing of the picture, which were just right.
Granted, I'm no expert in photography or anything, but its a very excellent job and a great effort on your part.
