I am with Rob,
The crop is a shocker. Perhaps clone out the shadow if it is a distraction but the pavement provides a base to the wall and places it all more in context.
The real trick is to see the final crop when you are shooting and make it all final from the start.
OK everyone fair doos
I am big enough to say that I might be wrong this time and yes I would have also preferred the shot with some side walk in front of it, to allow the viewer to travel into the image, but I seemed to get stuck on the shadow rather than looking at the rest of the image, so thought it might help the composition by cropping it out. But as everyone here also seems to agree, it is better to crop in the camera and to achieve this, I would have walked further into the shot (waiting for the traffic to leave enough time for me to do so of course), to find a composition that removed the shadow but also made more of the side walk without a shadow, but perhaps that is just my style of working.
