I think the B&W conversion has worked well Maureen, and your composition is excellent. Unfortunately for me the blown out highlights in the sky and building at the top of the image makes my eyes wonder in that direction. Also the blown out part on the right is also drawing my eyes away too, sorry.

I'd also have liked to see a little more detail in the shadows too to bring out more detail.

It really can be hard to expose for a scene like this with a lot of white but otherwise a great composition. Experiement with your metering modes a little more to get the exposure especially when all the whites will confuse the censor in matrix mode. You can also try auto bracketing as a safety measure to help get the right exposure.
