The red waves

Beautiful lines, shapes, and colors. The triangular shadow at the bottom is a bit distracting, but cropping it out might make a less satisfying composition in terms of the proportions of the remaining building. Is there any chance of recropping to add a bit more of the shadow? That might turn it into a compositional element that would direct the eye to the windows rather than competing with the windows for attention. But it's a very nice image in any case.
