The black and white I think would have been better Sepia. but the image is taken from the right point.. I like the standpoint in this. When we look at Liverpool history, it is coming out of a dark point in it's history, so a darkened image is the way forward I think to bring out the sombre nature of the docks.
Furthermore.. Albert dock is excellent to photograph at night, I think this is because the contemporary bright lights of modern commericialism and the sombre brickwork provide a wonderful contrast.
