A sequence by definition has a specific order, it has a start, a middle and an end – a transition of idea from start to finish. A series consists of related parts whose resonance helps build their meaning. These images need not be seen in a specific order. Serial images rely on multiplicity to drive home their meaning and can generally be arranged in any sequence to create the same conclusion.
By definition these photographs must be related in some way. Your images should tell a story rather than just follow a sequence. Remember that story telling is as much about what you chose to edit out as it is about what you show us. A truly successful set of narrative images have merit and interest as individual pieces as well as within the group.
