I like it. The composition brings in a nice dynamic and the mannequin without a head is good end or start point to read the picture.
Losing your head is the province of the last guy in line, and why you should never turn your back on anyone, depending on him to save
your skull. Morality play, or at least a warning on current politics.
If through no fault of your own you
are the last guy in line and only look forwards, who the hell do you imagine is minding
your ass? And if you do the right thing and mind the rear, how can you be certain you are still moving in the right direction and won't turn around to discover yourself walking backwards all by yourself? The humiliation!
Object lesson: fish never swim in line any more than wildebeest run that way. (Elephants often do walk that way, but who's gonna bug them?) When wildebeest do form rough lines, they end up inside crocodiles.
