Houses of Parliament.

Big Ben and the Houses of Parliament silhouetted against the

changeable London sky, viewed from across the River Thames.

lovely image. I would crop the bottom up to the "structure" in the middle of the water...the sky is blown out, and the buildings too dark...you can prevent this problem by using a graduated Neutral Density Filter to darken the sky a bit, and allow for more exposure time to brigten up the buildings and show more detail...hope this helps...keep shooting and posting!
