I think there is another photo of the same building in this challenge. I prefer your photo. I like that you filled the frame. It's an amazing building.
Nice simple composition. Simple in terms of no distracting elements (although I think actually the triangles could have made a great image without the lamppost too), and simple color scheme.
The lamp post gets lost in the sea of triangles. I would have scored this higher if the lamp post was featured and you found an angle to shoot that would show at least 2 different hues of trianges.
