Looking out for line, shape and texture in architecture and urban photography

Anyone who sees my work would surely know that I am a sucker for shapes and composition.  Truth be told it is often the shapes with in image that attracts to taking the photo in the first place.

I think the image above highlights that clearly enough.  I took this shot because I was attracted to the triangular elements at the top and bottom of the shot as well as the strong diagonals of the grey concrete.  I was also attracted to textures within each element - the horizontal lines in the dark brick work against the strong verticals in the grey concrete and the diagonals within the gold metal elements show a nice interplay (if that is the right word) of the materials used.

What do you think? Do you see similar elements when you create your photographs?  What is your approach when creating shots like this?
