If one was to present the same scene and camera gear to ten different photographers, you'd get ten different photographic results. In Akira's series, great compositional weight has been given to the un-illuminated areas.
His placement of the large, dark areas is, IMO, somewhat unconventional in terms of contemporary trends in compositional style.
My own reaction is that these shots remind me of a feeling of 'let down' I often get after a brilliant day ends, and I notice the now-dark areas of the cityscape are now providing me with less to look at, less to see, less to photograph. The usually supplied artificial lighting rarely provides me with the quantity of visual opportunities that daylight does.
