Angular Buildings

I'm not 100% sure on todays post. I took these images because I liked the strong angular lines of the buildings against the plain blue sky. When I looked at them I felt that I liked them /because/ of the theme, and not without it. As such I thought I would try them as a dual image - I suppose given "bloggers block" I should really be separating them over multiple days.
