It has a branching, tree-like look itself - is that accidental or did they design it that way, I wonder. I would get rid of "Iron Age" - or use it as my title :) Great textures and light/shadow play. Did you try a vertical flip - and then maybe a horizontal flip, too? Now you WOULD have to clone out the letters :)
Lovely pattern. Great processing. At first I thought it was an imprint in the sand from the bottom of someone's sneakers, like this one of mine but then I saw it was way too precise to be that.
ETA: This IS really striking. I keep coming back to look at it again.!!
what a lovely graphic - at first I thought it was a fantastic pattern in the sand, made by seaweed. perhaps. you have shown us a wonder from industrial humankind.
