Actually it was very much about the geometry, and the interplay of contrasts between the shadows and reflections, cement and glass, organic and inorganic.
Some of the lines aren't exactly horizontal because I wasn't shooting directly straight at the wall, but theres a lot going on in the image that I like (albeit very slowly).
Thank you very much for sharing your kind words jaragaki.
This is a real pice of art. The ratios here are near golden ratios. I'm wondering if that was intentional. If so, bravo!; if not, well, it came off really well! Either way, the climbing plant adds some chaos to the strict proportions. Brilliant photo!
