These are of a motorway overpass down the road from me, interesting lines and shadows I thought. I took these in the middle of the day, bright sun and wind made for some issues! That said, I do quite like some of the subtleties in the shades of grey on the underside of the bridge.
I wasn't entirely sure how much I should be manipulating them on my computer. I've adjusted the contrast on 2 of them, but pretty much left them alone other than that.
