The reason for a SBS is to show the intermediate steps.

This is great and very interesting.

It's an older piece not made specifically for this contest...and as such no record of progressive steps were made or kept...(but I could probably re-create or explain if there's any questions as to a particular area...)

Having looked at the original image in the SBS this looks mostly the result of a particular free filter I can't remember the name of. I could be wrong mind you. Either way it's interesting to me at least...I like images that inspire the viewer's brain to make its own interpretation.

Parts of it were as easy as mirroring an 'object' together...others, not so much... The bottom left 1/4 has some major work. It's a miniature cathedral...
