Hi Martin,
At first glance, IMO this image can fall into one of two camps.
Either it is a simple candid, but if this is the case, it lacks any purpose or a "raison d'etre" for being taken, apart for what ideas were on your mind at the time of taking, which, to me, are not being successfully conveyed through the image alone.
Or it is an abstract of the people at that time and place, but, if this is the case the composition could (IMO) be improved by the addition of a couple of modifications.
1. A lower POV with the camera kept horizontal, to give all the people the same point of reference in height (maybe here it would be about thigh height) and simultaneously this would remove the distracting converging verticals.
This would force the eye to search for pattern and repetition.
2. A tighter framing that excluded the extraneous body parts either side of the image, and hold focus on the middle five subjects.
Either way, Martin, I would love to hear your personal views of the image, what it meant to you and why you took it,
