At first I had no idea
This work succeeds at one thing for me, and that is that it got my attention. I looked, thought, and looked, and I still am coming up with ideas as to what's going on. I like how you didn't overdo the details on the bodies, they are deformed enough to make a point but not so much as to distract. The one thing I would change about the work is the white outline around the figures, I think they would fit with the background better that way. Good work.
