That's why I said that I was surprised by this image here.I thought that might be the case, especially given where the OP lives. But whether or not the image would be meaningful to anyone not cognizant of that meaning, is debatable. I seldom find something ambiguous (per Amolitor, above) to be good art ... and without a needed background explanation, this looks like just another attempt at a scary "Big Brother / Dystopia" type image. And IMO, if an image needs a background explanation to be meaningful to a certain audience, than the wrong audience is being targeted.
EDIT: I did do some quick searches for obvious keywords, and was unable to find that symbol / helmet... so am assuming it is relatively obscure?
Helmet appears to be of Soviet WW2 model with painted by hand Polish insignia, a white eagle, in this case without the crown. That suggests use in Polish Armed Forces organized and equipped by USSR government in 1943. It was supposedly communist army, thus lack of the crown. It was very much a political creation, nevertheless it was a real, fighting unit. Maybe in today political atmosphere in Poland the effort of that army is degraded and forgotten, like face if that figure wearing the helmet.
It might very much be so. In that case I would like to see more casual props.I do not think this image need any commenting, to be honest, because the OP summed it up very well: playing around with lighting.
That's exactly what it is to me, nothing more, nothing less.
