Another photo I took of one of the four towers clustered together on Paseo de la Castellana in Madrid.
Details of the photo: 1/100s at f/11, focal length 24mm, ISO 200.
I like this photo because of the shape of the building: how the the lower part curves to the right as one looks up the building, and the curvature of the top part of the building. The reflection of the cloud on the right side merges nicely into the cloud behind it; it almost looks like the cloud is sitting outside the window. There's little input from me on the composition; the building speaks for itself. Comments are welcome.
