Very cool on a whole bunch of levels! And pig butts? Are those pig butts? Legs below the pig butts. The whole relationship thing, squared, sorta. Pi squared as well. And who's the statue head guy?
Your tools in the foreground rather spoil a very nice image, but they do make a point relative to the challenge. I think the arch itself would have been adequate to meet the challenge. I really like the spring flowers and the couple with the picnic.
I wonder why you chose to use the CD and ruler when you have that great stone "pi symbol" in the background? To be honest the CD and ruler take away from the image rather than add to it. Have a go at getting low and shooting the stone sculpture with those flowers out of focus in the foreground - just an idea
Clever. There are too many main features in one shot. Unfortunately, the building in the background is a major one (the strong window crossbucks, white frames, and tan wall - strong contrasts) - to blur it but not the Pi, ruler or CD would be a real challenge.
