I know this vantage point, the Mong Kok Street pedestrian overpass, a great place to watch people. Last time we were in HK, we stayed at the Royal Plaza Hotel and walked on this footbridge many times. I forgot the name of this street. Is it Fa Yuen or Tung Choi Street?
I took shots of this street in both day and night and not satisfied with the result. May be it was my tight vertical framing. I like how your horizontal signs extends the lines between the tin roofs.
I took this shot from the other side of the overpass.
