Catherine Ning-the wall

This is a picture I took in the campus. I lean on the fences and shot it. I especially love the complex colors of the brick in the wall, and it seems that the the bricks are moving. The blue color of the window is excellent too.The windows also made a perfect angle towards the front, and there is a triangle on the right on the corner.The only flaw of the photo is there are some distracting cars and a trash bin.
