If the center of interest is meant to be street life itself, then the major elements need to be well placed within the frame and visible. Overhead light in BKK has a lot of glare and shadows are deep.
IMO, to be impactful, the image should have been composed so that the frame is much more full, to give the impression of activity, and the couple and tuk-tuk need to be lightened so that they are visible and not just murky objects.

The placement and see-ability of the major elements are more than subtle hints to the viewer what he/she should understand as important; the placement and see-ability tell the viewer what the photographer sees as important and makes a bridge between viewer and photographer.
I couldn't find an equivalent picture to show what I mean but here is one where the placement of the elements makes really obvious what the people were doing and what I saw as interesting.
I hope this is useful.
