I have to visit Seattle one of these days if you have skies like this ... I live about 90 miles south of San Fran and it's almost always just blue skies or fogged over .. no drama .. Beautiful textures on those buildings leading my eyes right up to that sky. Just lovely.
Building and sky actually have a lot in common in this image. They seem to mutually enhance each other. An excellent composition. (You had great light too.)
