Hope I not being infested with camel fleas if I notice that the first part of your pan before the bridge definitely does not look good. It's first when you reach the bridge and slow down it's worth looking at. Maybe you should have stayed a little bit further away from the bridge so you had the whole bridge in the shot. Otherwise it's a nice smoot yaw.
Is there some missing railway tracks on the bridge or is the train so wide in Canada ?
