You hit a home run on this photograph and it's hit me quite well. The stark contrasts between the ground, walls and the people mixed in with the metallic texture of the camera mounts work so well together.
The angle it's shot in is amazing. You feel like you're a stout security camera ever vigilant to what's going on. This is an original idea I've not seen anywhere else. I've seen the angle before, but not how you portrayed it.
I wish I could write more, but I feel I've summed up my feelings rather well.
