Basically it reminds me of some kind of industrial, and mechanical structures, like in the Matrix, Zion City.
The lock somehow looks like a lift, or some kind of transportation for people moving to and fro on the platforms resembled by the structures of the door.
The solitary of the lock, and its presence among the overwhelming 'latforms' which is the door, made me think of or felt the kind of the feeling when we are confronted with the overwhelming size of man made marvels, such as the WTC, the Great Wall, etc.
Imagine standing at ground level, and looking up to see the top of a skyscraper, or looking down on a high level inside the building.
I'm always memorized by the sheer size and complexity of architectures.
AWESOME!!

Thanks!
I did cross-process it, but the final effect is additional to it.
