Thanks for the comments.
When I posted this, I was interested to know whether the woman modelling and the photographers in the background were obvious enough, as they show an important juxtaposition between women's jobs, and, judging by the comments, I think the answer is "not really".
Maybe I can rectify that with a bit of judicious PP. Maybe brighten the red lanterns and change contrast, brightness and maybe even the colours of the background figures to help them stand out a bit more.
Actually I have had to make the best of a poor job with this image, as I came around the corner of the alley and was confronted with the scene, which delighted me. However, my lens was wide open, giving me less depth of field than I thought I had, and also the AF focus area had been knocked to the bottom, and was focused on the pavement just in front of the women, which has actually been cropped off here. I wanted the model shoot to be very slightly out of focus to be a secondary, but recognisable, sub-scene, but not attract too much away from the hard-working main subjects, but it was far more blurred than I had planned, and had to be rescued a bit in post.
My first attempt was to take them whilst still much nearer the model shoot, but this did not work because the angle meant that the second and third women were hidden behind the first, and anyway, I later discovered my mangled AF point meant that nothing much was in focus. I then decided to shoot wide angle as they went past to accentuate the leading lines toward the model shoot. I didn't want to stand there, camera to eye, as they walked past, as a clown with a camera pointed at them as they toiled past with their load may have hurt their feelings, so I just dangled the camera from my hand and trusted to instinct, as this also gave the low angle I needed. So the clown still fired (silent) shots as they walked past, but I am sure they were unaware and didn't feel any anguish, which I think is most important, even if the result is the same.
Human failure on my part meant that the result was technically sub-optimal, and you can't make a silk purse from a sow's ear, but sometimes the purse you do get is still useful, especially if the subject and story is strong enough.
