Nice, I like it, has lots of grey! But doesn't this building make you want to have a technical camera to get rid of the converging lines? My fingers would itch to come back to this with the monorail.
You got a very good point. Either get rid of the converging lines all together, or use a wide angle, move closer and make the lines more convergent. This is shot with a normal lens; making the converging lines appearant, but not enough to make a creative effect. I shot it mainly because of the reflection in the windows.
