Definitely interesting structures, well done getting it almost perfectly symmetrical as its very difficult from what I have found in the past.
Nice one - Didn't know you could get that close!
Well, that's neatly done. I was thinking along the same lines....
Crop and rotate in Lightroom …. Thanks all, unusually it was the shot i planned to take that made it to the finished product.Agreed, it's hard to get the shot central and symmetrical. Well done - works nicely in mono.
