The light on the dome really creates an unusual effect. I would love to see this with the modern day doo-dads (vent, etc) cloned out but that would be a lot of work.
A well composed photograph, light could have been better to enhance the detail. The modern day ductwork, front and centre, detracts from the beauty of the building.
There is some sort of halo all around the dome, that is very distracting and really takes away from the photograph. I do like the green dome, it stands out among the muted colours of the brick.
