sometimes when you see a candid shot taken in a street it just jumps out at you, this is one of those photos..why?
well the expression of the man in the middle, he has obvious made a visual contact with the photographer but is not not showing anger, more bemusement or intrigue that someone would take his photo. Even though he is an interesting subject in his own right (by the fact that he is carrying his heavy 'shopping' on his head). the woman on the right is indifferent, she probably didn't see the photographer but is interested in the motorcyclist, maybe the cyclist shouldn't be there? did he take a short cut through a pedestrain area? This all adds to the story and the interest in this photo. The fact that the photographer has also captured the hussle and bustle well too, note the person to the very right of the photo, we can hardly see a shoulder but we get the feeling that they are moving as the rest of the image is.
nicely captured, the backlight/bright light only adds to the effect of a busy area.
