While I agree that the skyline could be updated, I have a few problems with your image. There are two skylines, with only a few images to represent the city there shouldn't be any repeats. The top skyline isn't a complete representation of the downtown, it is missing the tallest building in the prairies, as you have mentioned. The Olympic Park and zoo images are too small to make out. And the image of the Bow is without context, losing its landmark value.
