There is something that I find quite disturbing about this statue. It has echoes of Fritz Lang's "Metropolis", and of Olympian achievement, but there are also dark echoes of events in the 1930s. It dominates the area in which it stands - you can't ignore it.
I had to look up Fritz Lang and Metroplis... I could, however sense something untoward, even without your backstory. Your choice of this high contrast appearance feels adds to the ominous feeling that you say you felt just standing there. Personally, I find faceless human forms to be disturbing...and these appear very robotic to me...and thus feel quite alien.
You photographed and processed this perfectly for what you felt, Bill.
