This is a ideal image for either the transparency contest or reflection. What an amazing place to see able to take this shot, I would have never guessed that this was a museum. I love the placement of where you took the shot from as well as the composition. The image seems so peaceful, possibly from all the blue. I also really like that you can sees a little sail boat out on the water as well as people outside the building. The only I would comment on is those small reflections in the windows in just a few small place. Overall I think you did a great job, people may have just voted it higher in the reflection category.
I like it. If I'm being really picky I clone out the people on the left and I use a polarizer to remove the mild reflections in the windows. Good capture though. 7
