Since you didn't get the whole of the top of the window frame in the picture, I think you should 'rethink' the crop. It might look better cropping it more at the top so that it matches up with the bottom of the picture.
Architecture, museum, window frame, lighting, high class education perhaps...I loved the lines and architecture but I had to rub my eyes before education became the focal point. I enjoyed the dim visual shapes seen in the middle and upper right corner shadows away from the window. Thanks for the photo.
