Beginner's question: opinion on cropping

Well this thread got interesting. I don't care how a photographer I am. I always try to shoot with composition in mind but if I can't then I crop and I don't care what anyone thinks.

We were in Portugal when I took this shot on a bus tour to Lisbon. A terrible day for me because it was as spectacular foggy morning and the bus does not pull over when you want to shoot.

I set my cam on AI servo and shot this through the bus window at highway speed. About 80 KPI.

The original.
