/ic/ - Artwork/Critique

I want to find a focal subject for this image.

The idea is that some kind of industrial supernatrual event has taken place. The broken barrier suggests that an area formerly under control is now unchecked. Something awful has happened.

But this has to keep in line with the aesthetic of the image - sterile and unnatural.

Also I want to keep the shaded patch on the fence, currently cast by the undefined dark object behind it. Don't know what that object is yet... was thinking of maybe a big sign with a worning on it...

If anyone has any narrative suggestions for the above then I'm open
